Church–state relations in Spain: Variations on a National-Catholic theme?

Contrary to the absence of a uniform Spanish identity (a phenomenon that is often referred to as Spain being a ‘nation of nations’), Spain’s confessional map is remarkably homogeneous. From the beginning of its existence as a political conglomeration, Spain has been a mono-confessional Catholic territory. Even at present, Catholicism is an intrinsic feature of Spanish society and – though officially a secular state – of state policy. A closer look at Spain’s religious situation and its corresponding pattern of church–state relations reveals, however, some recent cracks in the century’s old bond between Spain and Catholicism. Particularly secularization and religious pluralism challenge Spain’s mono-confessional Catholic nature, a development that fits well into Spain’s post-Francoist focus on Europe and European (secular) values. This paper discusses Spanish church–state relations from the beginning of its political existence until present times. Special attention will be paid to more recent societal developments and their impact on religious Spain and church–state relations.

From multi-confessional to mono-confessional state. State–church relations in Poland following World War II

According to Madeley’s (2003) comparative framework of state–church relations in Europe, Poland is part of the historic Northeast-Southeast multi-confessional culture belt. The aim of this paper is to analyse the historic relationships between the Polish state and church in relation to this framework with special attention to the post-Second World War period and to the consequences for the Polish religious landscape. In contrast to the multi-confessionality of the historic Polish polities, after the Second World War Poland became a mono-confessional, Roman-Catholic country. Territorial changes, the resettlement of people and the annihilation of the Jewish population by the Nazis were responsible for this religious homogenisation. Consequently, the relationship between state and church was almost completely confined to the relationship with the Roman-Catholic Church. During the 45 years of communist dominance, that church became the largest public organisation independent of the state authorities and played the most important role in the struggle against the ‘atheisation’ of Polish society as a consequence of the strong support for the church by the majority of people. The post–1989 period is characterised by a liberalisation towards non-Catholic religious communities and – after an initial reluctance – a positive attitude of the Polish Roman-Catholic Church (strongly supported by the Polish Pope John Paul II) towards the Polish membership of the European Union.

On the miscibility gap in monazite–xenotime systems

The regular solid solution model has been applied to solid solubility in the monazite–xenotime systems and is verified against the available experimental data for LaPO₄–YPO₄ and CePO₄–YPO₄ systems. The model is then used to predict the miscibility gaps in a number of other monazite–xenotime systems. The implications for prospective two-phase monazite–xenotime fiber coatings for applications in ceramic matrix composites (CMCs) are discussed.

Regional-scale Proterozoic IOCG-mineralized breccia systems: examples from the Wernecke Mountains, Yukon, Canada

A large scale Proterozoic breccia system consisting of numerous individual breccia bodies, collectively known as Wernecke Breccia, occurs in north-central Yukon Territory, Canada. Breccias cut Early Proterozoic Wernecke Supergroup sedimentary rocks and occur throughout the approximately 13 km thick deformed and weakly metamorphosed sequence. Iron oxide–copper–gold ± uranium ± cobalt mineralization is associated with the breccia bodies and occurs as veins and disseminations within breccia and surrounding rocks and locally forms the breccia matrix. Extensive sodic and potassic metasomatic alteration occurs within and around breccia bodies and is overprinted by pervasive calcite and dolomite/ankerite, and locally siderite, alteration, respectively. Multiple phases of brecciation, alteration and mineralization are evident. Breccia bodies are spatially associated with regional-scale faults and breccia emplacement made use of pre-existing crustal weaknesses and permeable zones. New evidence indicates the presence of metaevaporitic rocks in lower WSG that may be intimately related to breccia formation. No evidence of breccia-age magmatism has been found to date.

Tectonics of the Simplon massif and Lepontine gneiss dome: deformation structures due to collision between the underthrusting European plate and the Adriatic indenter

This study presents a review of published geological data, combined with original observations on the tectonics of the Simplon massif and the Lepontine gneiss dome in the Western Alps. New observations concern the geometry of the Oligocene Vanzone back fold, formed under amphibolite facies conditions, and of its root between Domodossola and Locarno, which is cut at an acute angle by the Miocene, epi- to anchizonal, dextral Centovalli strike-slip fault. The structures of the Simplon massif result from collision over 50 Ma between two plate boundaries with a different geometry: the underthrusted European plate and the Adriatic indenter. Detailed mapping and analysis of a complex structural interference pattern, combined with observations on the metamorphic grade of the superimposed structures and radiometric data, allow a kinematic model to be developed for this zone of oblique continental collision. The following main Alpine tectonic phases and structures may be distinguished:

Metamorphic zoning and geodynamic evolution of an inverted crustal section (Karakorum margin, N Pakistan), evidence for two metamorphic events

The Karakorum Range comprises a crustal section of marbles and metapelites providing an opportunity to study the extent of high-temperature metamorphic reequilibration in an active orogen. Metamorphism culminated during the Mio-Pliocene, at 6–7 Ma. Peak metamorphic conditions increased from south to north, i.e. from (1) the Upper Anchizone grade (lawsonite, chlorite–smectite) to (2) lower granulite migmatite grade (HT∼800°C) conditions along strike of a 30-km section perpendicular to the structural fabric of the rocks. The metamorphic section can be separated into two domains:

The aeolian sedimentation record of the Thar desert

A review of the aeolian sedimentary record of the Thar desert is presented. This includes a regional survey of the major dune forms, their genesis and their relationship to climate and other regional landforms. A key aspect of this work is the chronometry of the dunes using luminescence methods. Luminescence dating of sand has enabled quantification of the duration of the phases of sand aggradation and quiescence, time scales of dune migration and the dating of pedogenic carbonates. We demonstrate that the conventional wisdom of synchronicity of dune aggradation with glacial epoch is not true in the context of Thar sands and here only a short durationwindow of opportunity existed for dune aggradation. Luminescence ages further suggest that this window occurred during a transitional climatic regime from glacial to interglacial about 4–10 ka after the glacial epoch. Other inferences included are that:

New data on the Neoproterozoic – Cambrian geotectonic setting of the Teplá-Barrandian volcano-sedimentary successions: geochemistry,U-Pb zircon ages,and provenance (Bohemian Massif,Czech Republic)

The Teplá-Barrandian unit (TBU) of the Bohemian Massif was a part of the Avalonian-Cadomian belt at the northern margin of Gondwana during Neoproterozoic and Early Cambrian times. New detrital zircon ages and geochemical compositions of Late Neoproterozoic siliciclastic sediments confirm a deposition of the volcano-sedimentary successions of the TBU in a back-arc basin. A change in the geotectonic regime from convergence to transtension was completed by the time of the Precambrian-Cambrian boundary. The accumulation of around 2,500 m Lower Cambrian continental siliciclastics in a Basin-and-Range-type setting was accompanied by magmatism, which shows within-plate features in a few cases, but is predominantly derived from anatectic melts displaying the inherited island arc signature of their Cadomian source rocks. The geochemistry of clastic sediments suggests a deposition in a rift or strike-slip-related basin, respectively. A marine transgression during Middle Cambrian times indicates markedly thinned crust after the Cadomian orogeny. Upper Cambrian magmatism is represented by 1,500 m of subaerial andesites and rhyolites demonstrating several geochemical characteristics of an intra-plate setting. Zircons from a rhyolite give a U-Pb-SHRIMP age of 499±4 Ma. The Cambrian sedimentary and magmatic succession of the TBU records the beginning of an important rifting event at the northern margin of Gondwana.

Influence of hydrogen on Fe–Mg interdiffusion in (Mg,Fe)O and implications for Earth’s lower mantle

Interdiffusion of Fe and Mg in (Mg,Fe)O has been investigated experimentally under hydrous conditions. Single crystals of MgO in contact with (Mg_0.73Fe_0.27)O were annealed hydrothermally at 300 MPa between 1,000 and 1,250°C and using a Ni–NiO buffer. After electron microprobe analyses, the dependence of the interdiffusivity on Fe concentration was determined using a Boltzmann–Matano analysis. For a water fugacity of ∼300 MPa, the Fe–Mg interdiffusion coefficient in Fe _x Mg_1−x O with 0.01 ≤ x ≤ 0.25 can be described by with and C = −80 ± 10 kJ mol⁻¹. For x = 0.1 and at 1,000°C, Fe–Mg interdiffusion is a factor of ∼4 faster under hydrous than under anhydrous conditions. This enhanced rate of interdiffusion is attributed to an increased concentration of metal vacancies resulting from the incorporation of hydrogen. Such water-induced enhancement of kinetics may have important implications for the rheological properties of the lower mantle.

Calcium diffusivity in alumino-silicate garnets: an experimental and ATEM study

Concentration gradients in calcium are common in metamorphic or magmatic garnets and can be used to determine the timescales of geological processes. However, the kinetics of Ca diffusion in garnet is poorly constrained and experimental studies have to date yielded widely varying diffusion coefficients. In this paper, we describe a new method for generating diffusion profiles in garnet. We incorporated polished and compositionally homogeneous garnet seeds in a finely ground powder of clinopyroxene and garnet. During the experiments (1.3 GPa, 1,050–1,250°C, and ƒO₂ ≤ the graphite-O₂ buffer), the mineral powder partially melted, recrystallized, and formed a 10–50 μm wide overgrowth zone of compositionally distinct garnet around the seeds. Long duration experiments generated measurable relaxation profiles at these seed/overgrowth interfaces. We performed analytical transmission electron microscope traverses across the interfaces in each experiment. Thirteen usable compositional profiles were obtained with characteristic distances of diffusion ranging from 300 to 1,000 nm. From these profiles, Ca–(Fe, Mg) interdiffusion coefficients were retrieved using an analytical solution for the diffusion equation and the data were cast in an Arrhenius relation. Linear regression of the data yields an activation energy Q _{Ca–(Fe, Mg)} equal to 188 ± 48 kJ mol⁻¹ and a frequency factor D ₀ equal to 6.6 × 10⁻¹⁴ m² s⁻¹. Within the compositional range studied, the composition of garnet has no major effect on the Ca–(Fe, Mg) interdiffusion coefficient. The very slow diffusion rate of Ca is in agreement with natural observations indicating that Ca diffuses more slowly than Fe and Mg. The Ca diffusion coefficients derived from this study are not model-dependent and can be used to determine the durations of geological events from Ca relaxation profiles in natural garnets.

THERIA_G: a software program to numerically model prograde garnet growth

We present the software program THERIA_G, which allows for numerical simulation of garnet growth in a given volume of rock along any pressure–temperature–time (P–T–t) path. THERIA_G assumes thermodynamic equilibrium between the garnet rim and the rock matrix during growth and accounts for component fractionation associated with garnet formation as well as for intracrystalline diffusion within garnet. In addition, THERIA_G keeps track of changes in the equilibrium phase relations, which occur during garnet growth along the specified P–T–t trajectory. This is accomplished by the combination of two major modules: a Gibbs free energy minimization routine is used to calculate equilibrium phase relations including the volume and composition of successive garnet growth increments as P and T and the effective bulk rock composition change. With the second module intragranular multi-component diffusion is modelled for spherical garnet geometry. THERIA_G allows to simulate the formation of an entire garnet population, the nucleation and growth history of which is specified via the garnet crystal size frequency distribution. Garnet growth simulations with THERIA_G produce compositional profiles for the garnet porphyroblasts of each size class of a population and full information on equilibrium phase assemblages for any point along the specified P–T–t trajectory. The results of garnet growth simulation can be used to infer the P–T–t path of metamorphism from the chemical zoning of garnet porphyroblasts. With a hypothetical example of garnet growth in a pelitic rock we demonstrate that it is essential for the interpretation of the chemical zoning of garnet to account for the combined effects of the thermodynamic conditions of garnet growth, the nucleation history and intracrystalline diffusion.

Petrographic observations suggestive of microbial mats from Rampur Shale and Bijaigarh Shale, Vindhyan basin, India

Petrographic observations of two Vindhyan black shales (Rampur Shale of the Semri Group and Bijaigarh Shale of the Kaimur Group) revealed the following features:

Assessment of lightning-related fatality and injury risk in Canada

This article summarizes research completed to assess the risk of lightning-related injuries and fatalities in Canada. Although lightning mortality has declined significantly over the past century, it remains a common meteorological hazard that regularly kills and injures. Based on an analysis of media reports, vital statistics, hospital admission and emergency room visit records, and fire loss data, the authors estimate that on average about 9–10 lightning-related deaths and 92–164 injuries occur each year in Canada. The distribution of casualties reflects current provincial population and cloud-to-ground lightning densities. Consistent with similar studies in other developed nations, most lightning-related fatalities and injuries in Canada occur during the June-August summer season, coincident with peak lightning, and during the Thursday-Saturday period, most likely related to higher rates of participation in outdoor activities. The majority of victims are male, less than 46 years old, and engaged in outdoor recreational activities when injured or killed in a lightning incident. Media reports used in the study were found to underestimate both lightning mortality (36%) and morbidity (20–600%).

Hydrology of the coastal sabkhas of Abu Dhabi, United Arab Emirates

Water fluxes were estimated and a water budget developed for the land surface and a surficial 10-m-deep section of the coastal sabkhas that extend from the city of Abu Dhabi, United Arab Emirates, west to the border with Saudi Arabia. The fluxes were estimated on the basis of water levels and hydraulic conductivities measured in wells and evaporation rates measured with a humidity chamber. In contrast with conceptual models proposed in earlier studies, groundwater inflow is estimated to be small, whereas the largest components of the water budget are recharge from rainfall and evaporation from the water table. Estimates within a rectilinear volume of sabkha, defined as 1 m wide by 10 km long by 10 m deep, indicate that about 1 m³/year of water enters and exits by lateral groundwater flow; 40–50 m³/year enters by upward leakage; and 640 m³/year enters by recharge from rainfall. Based on the water and solute fluxes estimated for the upward leakage into the sabkha, 7–8 pore volumes of brine have entered the sabkha from below since the time the sabkha became saturated (7,000 years ago) as a result of the last global sea-level rise.

Conceptual problems with remote element synthesis

The notion of remote element synthesis has recently been modified to explain the presence of nucleogenetic isotopic anomalies and decay products of short-lived nuclides by injection of a small amount ofexotic nucleogenetic material. Even with this modification, remote element synthesis seems inconsistent with the following observations:

The spatial implications of the functional proximity deriving from air passenger flows between European metropolitan urban regions

Until recently the traditional spatial configuration of the European geography was based upon the core-periphery model. The ‘pentagon’, broadly defined as lying between London, Paris, Milan, Munich and Hamburg, was seen as the core area characterised by having the highest concentration of economic development in the European Union (EU), with the remainder of the European territory viewed as peripheral, albeit to varying degrees. In a number of cases such peripheral areas equated with clear regional disparities. The elaboration of the European Spatial Development Perspective (ESDP) (CEC, European spatial development perspective, towards balanced and sustainable development in the territory of the European Union, 1999) challenged this core-periphery model. European spatial planning policies, aimed at encouraging social and economic, and with ever increasing importance, territorial cohesion, seek amongst other aspects to encourage the development of a balanced and polycentric urban system. This paper adopts a network analysis approach to the analysis of air passenger flows between some 28 principal European metropolitan urban regions. The evaluation of these flows contributes to an enhanced comprehension of the spatial dynamics of the European metropolitan territory which goes beyond that deriving from the more standard analyses of the individual components of the urban system. Several indicators are used, deriving from gravitational modelling techniques, to analyse the complexity of the air passenger flows. A multidimensional scaling (MDS) technique is introduced in order to interpret and visualise the resulting spatial configuration and positioning of the different metropolitan centres within the conceptual European ‘space of air passenger flows’, thereby contrasting with the more traditional map-based geographical image of Europe, based upon Cartesian coordinates.

Outcrop signatures of relative sea level fall on a siliciclastic shelf: Examples from the Rewa Group of Proterozoic Vindhyan basin

The Rewa Group of the Vindhyan Supergroup in the Son valley begins with a thick (∼200m) dominantly shaly, shelfal succession, occurring between the Dhandraul Formation of the Kaimur Group (fluvial sandstone) below and Drammondganj Formation of the Rewa Group (marginal marine sandstone) above. Such a stratigraphic disposition indicates a sharp rise in relative sea level at the onset of Rewa sedimentation, inducing a shelfal depth to the Vindhyan basin. However, a number of wedge-shaped, sandstone/conglomerate bodies (maximum thickness 23.5 m) occur at multiple stratigraphic levels within the aforesaid deeper water shale succession, which appear to be of much shallow water origin representing regressive deposits. Though these bodies do not define a single physically continuous unit, either vertically or laterally, they are still designated by a single term ‘Asan Sandstone’ in the literature. On the other hand, the encasing shelfal shales are termed as Panna and Jhiri Shales, in accordance with their occurrence below or above the so-called ‘Asan Sandstone’. The present study reveals that in different sections spread over the Son valley, there are several discrete regressive wedges occurring vertically, and their depositional environment is also variable, ranging between braided fluvial, shoreface fan and braid delta. The features common to most of the regressive coarser clastic bodies are:

Secondary Fe–Mn-oxides in minerals heavily damaged by α-recoil: possible implications for palaeomagnetism

Sub-micron Fe,Mn-oxides in columbite–tantalite minerals are bound to metamict domains in the host. These nano-oxides are secondary minerals as the metamict zones formed through accumulation of damages from α-recoil, each of which in a small volume destroys the crystal lattice of the U and Th bearing columbite–tantalite host. Transmission electron microscope investigations demonstrate that the oxides fall in the compositional range of magnetite–jacobsite–iwakiite (Fe,Mn)₃O₄ and of hematite-type minerals along the Fe₂O₃–Mn₂O₃ join, i.e., minerals that are known to be major carriers of magnetic remanence. Measured magnetic properties of isolated columbite–tantalite crystals demonstrate in some samples magnetic remanence, which is bound to sub-micron pseudosingle-domain crystals rather than to the host. Thus, the magnetic remanence is not related to the formation of columbite–tantalite, but to the crystallization of the nano-oxides, which occur in metamict domains of the host and therefore are secondary. Depending on the content and distribution of U and Th, the nano-oxides may form diachronously within an individual and among several host crystals. Magnetic secondary nano-oxides are not restricted to columbite–tantalite minerals, but may occur in other minerals where high contents of Fe and Mn are associated with high contents of U and Th. Rocks that show the same spatial distribution for U and Fe, as for instance some red sandstones, may display magnetic properties that are controlled by recoil-induced growth of secondary Fe-oxides.

Movement,memory, landscape: an excursion in non-representational thought

This paper is an excursion in non-representational thought. The primacy of movement charges this creative geography. Movement as sensation, thought, matter and memory crystallizes in ongoing assemblages (effects) we term selves and landscapes. This movement ontology is animated by a stream of thought running through Bergson, Deleuze, and Massumi, and by Ingold’s temporality of landscape. Memory is vital, as past (virtual) and present (actual) coexist, pushing forward in duration, the dynamic continuation of movement and sensation. David Lynch’s film, The Straight Story, offers dramatic illustration of the entanglement of movement, memory, and landscape. Landscape is emergent as relational lines of movement, an ongoing meshwork of practices and movement signatures. Alvin Straight’s paced journey through Iowa on a John Deere lawn mower during autumn harvest is a road to reminiscence and reconciliation, an American sublime. Lynch’s movement-images and soundscapes are sensorial undulations that illumine landscape as movement of incorporation, ‘dwelling’ in the moment to moment, geographies of care. The take-home message is that we are nothing more and nothing less than agents, next selves, ‘passing’ through. The collective trace of our ‘passings’ constitutes the making and remaking of place.
