Aspects of the marine Cretaceous of China

The marine Cretaceous of China is distributed mainly in southwestern Xinjiang, the West Kunlun Mountains, the Karakorum Mountains and most parts of Xizang (Tibet), with findings even from Taiwan.The marine Cretaceous of China may be divided into three sedimentary belts according to the lithologic and tectonic characters, biological provinces and the different modes of deposition.On the basis of recent research on the Cretaceous marine strata and faunas in China, the lithostratigraphic and biostratigraphic sequences have been preliminarily established and the division and correlation of strata and boundaries between the Jurassic and Cretaceous, Lower Cretaceous and Upper Cretaceous, as well as Cretaceous and Tertiary outlined; the position of the beach line of the Laurasian landmass in China and the events of the tectonic movement and the transgression and regression during the Cretaceous period are discussed.

Particle size scales and classification of sediment types based on particle size distributions: Review and recommended procedures

This paper provides a review of different particle size scales, size class terminology and particle size distribution (‘textural’) classification schemes which are widely used in sedimentology, geomorphology, soil science, aquatic ecology and civil engineering. It is concluded that a revised system of size class nomenclature, based on the Udden (1898) and Wentworth (1922) schemes, provides the most logical and consistent framework for use with sediments and a wide range of other particulate materials. A refined scheme is proposed which has five first‐order size classes (boulder, gravel, sand, silt and clay), each of which has five second‐order subdivisions with limits defined at one phi intervals. The scheme is simple and intuitively easy to understand. The paper also provides a review of previous schemes that have been proposed to describe and classify sediments on the basis of the proportions of gravel, sand and mud, or sand, silt and clay using trigons (also termed ternary diagrams). Many of these schemes do not have a logical basis and provide limited or uneven resolution. New gravel, sand and mud and sand, silt and clay classification systems are proposed that are both more logical and provide greater discriminatory power than previous schemes; they are therefore more suitable for use in environmental and forensic investigations. A new Microsoft Excel^® program, freely available to download from http://www.kpal.co.uk , allows rapid classification of sediments based on the proportions of gravel, sand and mud and sand, silt and clay proportions and graphical comparison of the data for different sample groups.

排除火山岩系的复杂性产生的对区域地质调查和地层划分造成的干扰,综合生物化石、同位素年龄及地球化学特征等数据提出了江苏地区侏罗系—白垩系火山岩系地层的层序划分,建议将燕山运动以来侏罗系—白垩系火山喷发岩系的三大旋回所形成的各火山岩和火山碎屑岩组,包括龙王山组、云合山组、大王山组、姑山组、娘娘山组名称取消,并将其作为不同时期的火山喷发岩系夹层分别归入西横山组、浦口组、赤山组,同时将苏北地区的象山群也归入西横山组,将白垩系底界放在西横山组与苏南所见的象山组之间。     

Palladium, Platinum and Gold Concentrations in Fengshan Porphyry Cu–Mo Deposit, Hubei Province, China

Abstract: The Fengshan porphyry-skarn copper–molybdenum (Cu–Mo) deposit is located in the south-eastern Hubei Province in east China. Cu–Mo mineralization is hosted in the Fengshan granodiorite porphyry stock that intruded the Triassic Daye Formation carbonate rocks in the early Cretaceous (~140 Ma), as well as the contact zone between granodiorite porphyry stock and carbonate rocks, forming the porphyry-type and skarn-type association. The Fengshan granodiorite stock and the immediate country rocks are strongly fractured and intensely altered by hydrothermal fluids. In addition to intense skarn alteration, the prominent alteration types are potassic, phyllic, and propylitic, whereas argillation is less common. Mineralization occurs as veins, stock works, and disseminations, and the main ore minerals are chalcopyrite, pyrite, molybdenite, bornite, and magnetite. The contents of palladium, platinum and gold (Pd, Pt and Au) are determined in nine samples from fresh and mineralized granodiorite and different types of altered rocks. The results show that the Pd content is systematically higher than Pt, which is typical for porphyry ore deposits worldwide. The Pt content ranges from 0.037 to1.765 ppb, and the Pd content ranges between 0.165 and 17.979 ppb. Pd and Pt are more concentrated in porphyry mineralization than skarn mineralization, and have negative correlations with Au. The reconnaissance study presented here confirms the existence of Pd and Pt in the Fengshan porphyry-skarn Cu–Mo deposit. When compared with intracontinent and island arc geotectonic settings, the Pd, Pt, and Au contents in the Fengshan porphyry Cu–Mo deposit in the intracontinent is lower than the continental margin types and island are types. A combination of available data indicates that Pd and Pt were derived from oxidized alkaline magmas generated by the partial melting of an enriched mantle source.     

Text, talk, things, and the subpolitics of performing place

This article tells the story of how a group of Dutch and Belgian citizens organized themselves to promote an area that they valued, to put it on the map, to raise awareness about its qualities, and to protect it from urban and industrial development. Our theoretical perspective focuses on the performative and political aspects of this place-making process and the discursive and material practices involved. We connect this to Beck’s concept of subpolitics.Our findings show how the group performed this place not only through text and talk - giving the area a name, using their knowledge and expertise to raise awareness about its values, lobbying and cooperating with decision-makers -, but also through things - installing art objects and information signs that articulate certain characteristics and values of the area. Our findings demonstrate the struggles involved in these performances. The group involved multiple perspectives on what the important values and characteristics of the area are and on what strategies would work best in trying to influence decision-making and protect the area. However, the use of expertise as the main strategy to gain influence excluded the more critical and activist strategies and privileging archaeological and historical values and characteristics came at the expense of attention on agricultural and natural values.Our findings make clear that performing place cannot be taken to be homogeneous and that it inevitably involves multiple perspectives and demands. The struggles, power relations and dynamics of inclusion and exclusion that this multiplicity implicates reveal a form of sub-politics that involves both politicization and depoliticization. Also, it is a form of subpolitics that is more diverse and ambiguous than Beck’s conceptualization presupposes by its emphasis on the role of outsiders as a homogeneous group.     

非海相白垩系年代学和对比

从1800年代初最早确定的白垩系定义起,白垩系就包括了海相和非海相白垩纪的地层和化石。白垩纪是一个全球性气候温暖、海平面高、构造和火山活动强烈的世界。此时,多块大陆分解,几乎所有海洋都已打开,形成了与现代相近的海陆分布的地理图案。这一变革导致了全球生物群的区域化,给全球对比带来了困难。白垩纪的全球年代地层表是主要依据菊石和微体生物(有孔虫和钙质超微浮游生物)化石,并与已完整建立的全球极性倒转年表和很多放射性同位素年龄相结合的产物。从孢粉到恐龙等各类非海相化石均已用于白垩纪生物地层学。此期专刊的特色是聚焦于区域或全球的孢粉(包括沟鞭藻)、大植物、甲壳类(包括叶肢介和介形类)、软体动物(包括腹足类和双壳类)和脊椎动物(包括硬躯体和足印)非海相白垩纪生物地层学和生物年代学。这些研究大大扩展了非海相白垩系对比的内容,并强调了将能取得更多进展的研究方向。非海相地层和化石群中直接夹有海相地层和化石的剖面/地区的非海相生物地层学更精确的研究,高分辨率的微体化石,特别是既出现于非海相又见于海相地层中的微体化石的微体生物地层学的进展,更多的直接与非海相生物地层学相关的放射性同位素和古地磁年龄的测试,非海相地层的高分辨率层序和旋回地层学分析及与非海相生物地层学对比的化学地层学的发展等,均将促进全球非海相白垩纪地层时代和对比,甚至以国际地质时标为准绳的全球非海相白垩纪地层对比框架表的建立。

论中国前寒武纪地质时代及年代地层的划分

本文讨论了前寒武纪地质时代和年代地层划分的原则和命名,提出建立隐生宙、原生宙和显生宙。隐生宙包括冥古代和太古代;原生宙分始元代、中元代和新元代。划分中的重要改变是根据新的年龄值数据将五台群归入太古代,将长城系底界改为1700Ma;并根据蠕虫-须腕动物群的出现,将震旦纪归入古生代。文中还阐述了作者对前寒武纪时代划分的新观点。
