湖北省红石地区叶家小湾金矿基本特征及找矿模型

红石地区叶家小湾金矿形成于燕山晚期，成矿流体主要来自岩浆期后热液。断裂和岩浆岩是两大重要的成矿地质条件。控矿构造为北东向断裂，花岗岩是金矿的有利赋矿围岩。成矿物质来自深部，与燕山晚期 浆活动密切相关，叶家小湾金矿综合找矿模型的建立，对于在红石地区开展找金（银）工作具有重要指导作用。     

安徽休宁—歙县东南部地区金多金属矿控矿构造研究

通过分析皖南休宁天井山金矿床和小贺铅锌矿床的构造控矿因素,认为燕山晚期花岗岩和北东向断裂是安徽休宁—歙县东南部地区金多金属矿形成最重要的控矿因素。歙县南源口和休宁桃溪两个地段的构造分析表明,该区中生代以来至少经历四期构造变形,其中早期向北西的逆冲推覆和北—北东向左行平移断层是成矿前构造;燕山晚期北东向高角度正断层控制燕山晚期花岗岩类侵入和成矿,是成矿期构造;随后的右行平移断层为成矿后构造。     

福建省金矿成矿地质条件与成矿远景

福建省金矿与地层、构造、岩浆岩等成矿地质条件关系密切,金矿赋矿层位有８个,其中以前寒武纪麻源群、龙北溪组和中生代火山岩、火山碎屑岩层位为最主要。金矿主要分布在区域性断裂、火山构造、北东向与北西向两组断裂复合部位及火山基底起部位,韧性剪切带、推覆（剥离）构造发育地段,是金矿重要成矿部位。金矿成矿时代主要有前寒武纪和燕山期两个成矿期,两者在成矿时间上显示继承性,在空间上具有相关性。金矿化在前寒武纪与中     

滇东北矿集区云南富乐厂铅锌矿区断裂构造控矿特征及其与成矿的关系

云南富乐厂铅锌矿床是滇东北矿集区东南部的典型矿床之一。在矿区进行大比例尺构造填图的基础上,运用构造成矿动力学的理论和方法,筛选典型断裂构造进行力学性质的鉴定,对不同期次、不同方向的断裂特征进行了系统阐述,初步划分了构造期次,总结了构造体系。认为该区断裂经历了晋宁期-澄江期近东西向的挤压作用,印支期-燕山早期北西-南东向挤压作用及后期燕山中晚期-喜马拉雅期的北东-南西向挤压作用的过程。晋宁-澄江期构造作用为该区成矿提供了有利的地质背景,印支期-燕山早期为该矿成矿主期,北东向压扭性断裂和北西向的扭张性断裂使得流体充填、富集成矿;后期近东西向的扭性断裂为破矿构造。通过矿区构造与成矿关系的研究,为隐伏矿预测与深部勘查提供了依据。     

论地穹区“三位一体”金的构造成矿及其有序性

本文以笔者所提出的构造矿源层(前寒武系变质岩区)+燕山期岩体(岩浆岩或火山岩)+断裂交汇部位(构造扩容空间)的金银-多金属构造成矿的模式(或谓“三位一体”构造成矿模式),对中国主要金矿的构造成矿、成矿控矿系列(构造成矿区、构造成矿带、构造成矿田、矿床和矿体的成矿定位)作了进一步的论述。指出了具有前寒武系变质岩的地穹区及其边缘断裂带为金的构造成矿富集区,并指出了金矿构造成矿的有序性规律及找矿远景区。     

哀牢山老王寨金矿田构造问题探讨

哀牢山老王寨金矿产于变质的晚古生代岩石中,是由浅变质的砂板岩、杂砂岩以及海相火山岩所组成。区内岩浆活动强烈,断裂发育。区内存在具挤压逆冲性质的东西向断裂带和显示塑性—脆性剪切带特征的NW-SE向断裂带,它们是主要的控矿构造。此外,有少量规模不大的NE-SW向断层,可切割上述断裂和矿体。根据对共轭节理测定、岩组分析和岩石有限应力分析等,本文对构造应力场作了划分:早期(成矿前)构造应力场发生于海西-印支运动期间;晚期(成矿期)构造应力场发生于燕山期,并可进一步划分早晚两个阶段。成矿主要受断裂控制,构造活动引起岩石蚀变,多次构造活动导致多次蚀变矿化。成矿时代为燕山晚期至喜山早期。     

查干布拉根银铅锌（金）矿床地质特征及成因类型

查干布拉根银铅锌（金）矿床是大型低硫化型浅成低温热液矿床，区域上受北东向裂谷型得尔布干断裂带及次级北西向断裂控制，矿床形成于燕山晚期大面积火山岩喷发及次火山岩侵位之后热 活动期，矿术具有独特的矿物组合与蚀变分带，主成矿元素分带明显，主要受北西西向断裂及其下盘的火山通道所制约，矿床形成深度较浅，剥蚀程度较低。     

个旧-大厂地区地质构造演化及锡多金属成矿

个旧-大厂锡多金属矿床不是简单的燕山晚期地台环境的“花岗岩岩浆期后气液矿床”，矿区地处三大板块的交接部位附近的个旧-大厂锡矿，前泥盆纪区域构造岩浆活动及锡多金属成矿作用强烈，泥盆纪-三叠纪裂谷作用和锡多金属成矿特点突出。泥盆纪受北西向同沉积断裂控制，在南丹-河池一带裂谷作用明显，发生了海底喷流成矿，加上印支-燕山期构造岩浆改造，形成了大厂锡矿。三叠纪受北东向个旧-兴义-晴隆同沉积断裂控制，在个旧、兴义一带发生的裂谷作用，伴随基性火山成矿、喷流热水沉积成矿和燕山晚期花岗岩改造(叠加)成矿，从而形成了个旧锡矿。

通过对高松矿田内主要断裂构造结构面、破碎带、旁侧派生伴生构造及其蚀变矿化等特征的系统深入观察研究，构造应力场分析，推断该矿田自中生代以来经历了印支期→燕山中晚期→喜山早期→晚近期的四期构造活动，其中燕山中晚期的构造活动为成矿构造；印支期活动为成矿前构造，其对成矿有一定的控制作用；后两期则为成矿后构造，其起到破坏矿体的作用。

The terrestrial fauna of the Late Triassic Pant-y-ffynnon Quarry fissures,South Wales,UK and a new species of Clevosaurus (Lepidosauria: Rhynchocephalia)

Pant-y-ffynnon Quarry in South Wales yielded a rich cache of fossils in the early 1950s, including articulated specimens of new species (the small sauropodomorph dinosaur Pantydraco caducus and the crocodylomorph Terrestrisuchus gracilis), but no substantial study of the wider fauna of the Pant-y-ffynnon fissure systems has been published. Here, our overview of existing specimens, a few described but mostly undescribed, as well as freshly processed material, provides a comprehensive picture of the Pant-y-ffynnon palaeo-island of the Late Triassic. This was an island with a relatively impoverished fauna dominated by small clevosaurs (rhynchocephalians), including a new species, Clevosaurus cambrica, described here from a partially articulated specimen and isolated bones. The new species has a dental morphology that is intermediate between the Late Triassic Clevosaurus hudsoni, from Cromhall Quarry to the east, and the younger C. convallis from Pant Quarry to the west, suggesting adaptive radiation of clevosaurs in the palaeo-archipelago. The larger reptiles on the palaeo-island do not exceed 1.5?m in length, including a small carnivorous crocodylomorph, Terrestrisuchus, and a possible example of insular dwarfism in the basal dinosaur Pantydraco.     

Définition d'une limite multicritère ; stratigraphie du passage Campanien–Maastrichtien du site géologique de Tercis (Landes,SW France)Definition of a multi-criteria boundary; stratigraphy of the Campanian–Maastrichtian interval of the geological site at Tercis (Landes,SW France)

Lithostratigraphy, physicochemical stratigraphy, biostratigraphy, and geochronology of the 77–70 Ma old series bracketing the Campanian–Maastrichtian boundary have been investigated by 70 experts. For the first time, direct relationships between macro- and microfossils have been established, as well as direct and indirect relationships between chemo-physical and biostratigraphical tools. A combination of criteria for selecting the boundary level, duration estimates, uncertainties on durations and on the location of biohorizons have been considered; new chronostratigraphic units are proposed. The geological site at Tercis is accepted by the Commission on Stratigraphy as the international reference for the stratigraphy of the studied interval. To cite this article: G.S. Odin, C. R.

The effect of water on accessory phase solubility in subaluminous and peralkaline granitic melts

The solubilities of columbite, tantalite, wolframite, rutile, zircon and hafnon were determined as a function of the water contents in peralkaline and subaluminous granite melts. All experiments were conducted at 1035 °C and 2 kbar and the water contents of the melts ranged from nominally dry to approximately 6 wt.% H₂O. Accessory phase solubilities are not affected by the water content of the peralkaline melt. By contrast, solubilities are affected by the water content of the subaluminous melt, where the solubilities of all the accessory phases examined increase with the water content of the melt, up to 2 wt.% H₂O. At higher water contents, solubilities are nearly constant. It can be concluded that water is not an important control of accessory phase solubility, although the water content will affect diffusivities of components in the melt, thus whether or not accessory phases will be present as restite material. The solubility behaviour in the subaluminous and peralkaline melts supports previous spectroscopic studies, which have observed differences in the coordination of high field strength elements in dry vs. wet subaluminous granitic glasses, but not for peralkaline granitic glasses. Lastly, the fact that wolframite solubility increases with increasing water content in the subaluminous melt suggests that tungsten dissolved as a hexavalent species.     

Late Wuchiapingian (Late Dzhulfian,early Late Permian) limestone olistolites within the Tertiary flysch of Glypia Unit (Mount Parnon,central–eastern Peloponnesus,Greece)

Some olistolites reworked in a Tertiary flysch of Mount Parnon (Peloponnesus, Greece) exhibit a Late Permian assemblage, dominated by Paradunbarula (Shindella) shindensis, Hemigordiopsis cf. luquensis and Colaniella aff. minima. This association corresponds to the Late Wuchiapingian (=Late Dzhulfian), a substage whose algae and foraminifera are generally little known. Contemporaneous limestones crop out in the middle part of the Episkopi Formation in Hydra, but they are rather commonly reworked in Mesozoic and Cainozoic sequences. The palaeobiogeographical affinities shared by the foraminiferal markers of Greece, southeastern Pamir, and southern China, are very strong (up to the specific level), and are congruent with the Pangea B reconstructions.
