一、YICHANG INSTITUTE OF GEOLOGY AND MINERAL RESOURCES——ACHIEVEMENTS OF RESEARCH(论文文献综述)

YAO Jianxin,BO Jingfang,HOU Hongfei,WANG Zejiu,MA Xiulan,LIU Fengshan,HU Guangxiao,JI Zhansheng,WU Guichun,WU Zhenjie,LI Suping,GUO Caiqing,LI Ya[1](2016)在《Status of Stratigraphy Research in China》文中提出Scientific research and productive practice for earth history are inseparable from the accurate stratigraphic framework and time framework. Establishing the globally unified, precise and reliable chronostratigraphic series and geological time series is the major goal of the International Commission on Stratigraphy(ICS). Under the leadership of the ICS, the countries around the world have carried out research on the Global Standard Stratotype-section and Points(GSSPs) for the boundaries of chronostratigraphic systems. In the current International Chronostratigraphic Chart(ICC), 65 GSSPs have been erected in the Phanerozoic Eonothem, and one has yet been erected in the Precambrian Eonothem. Based on the progress of research on stratigraphy especially that from its subcommissions, the ICS is constantly revising the ICC, and will publish a new International Stratigraphic Guide in 2020. After continual efforts and broad international cooperation of Chinese stratigraphers, 10 GSSPs within the Phanerozoic Eonothem have been approved and ratified to erect in China by the ICS and IUGS. To establish the standards for stratigraphic division and correlation of China, with the support from the Ministry of Science and Technology, the National Natural Science Foundation of China and the China Geological Survey, Chinese stratigraphers have carried out research on the establishment of Stages in China. A total of 102 stages have been defined in the "Regional Chronostratigraphic Chart of China(geologic time)", in which 59 stages were studied in depth. In 2014, the "Stratigraphic Chart of China" was compiled, with the essential contents as follows: the correlation between international chronostratigraphy and regional chronostratigraphy of China(geologic time), the distributive status of lithostratigraphy, the characteristics of geological ages, the biostratigraphic sequence, the magnetostratigraphy, the geological events and eustatic sea-level change during every geological stage. The "Stratigraphical Guide of China and its Explanation(2014)" was also published. Chinese stratigraphers have paid much attention to stratigraphic research in south China, northeast China, north China and northwest China and they have made great achievements in special research on stratigraphy, based on the 1:1000000, 1:250000, 1:200000 and 1:50000 regional geological survey projects. Manifold new stratigraphic units were discovered and established by the regional geological surveys, which are helpful to improve the regional chronostratigraphic series of China. On the strength of the investigation in coastal and offshore areas, the status of marine strata in China has been expounded. According to the developing situation of international stratigraphy and the characteristics of Chinese stratigraphic work, the contrast relation between regional stratigraphic units of China and GSSPs will be established in the future, which will improve the application value of GSSPs and the standard of regional stratigraphic division and correlation. In addition, the study of stratigraphy of the Precambrian, terrestrial basins and orogenic belts will be strengthened, the Stratigraphic Chart of China will be improved, the typical stratigraphic sections in China will be protected and the applied study of stratigraphy in the fields of oil and gas, solid minerals, etc. will be promoted. On the ground of these actions, stratigraphic research will continue to play a great role in the social and economic development of China.

王训练,周洪瑞,王振涛,沈阳,于子栋,杨志华[2](2019)在《扬子板块西北缘早中泥盆世构造演化:来自略阳地区踏坡组岩石学、锆石年代学和微量元素组成的约束》文中研究说明碧口地块北缘下中泥盆统踏坡组的物源长期被认为来自碧口地块新元古界基底——碧口岩群,但一直缺少碎屑锆石物源数据的支持。本文对略阳地区泥盆系踏坡组不同层位的3个碎屑岩样品开展了系统的岩石学、锆石岩相学及其U-Pb定年和微量元素组成研究。锆石晶体特征对比分析显示,研究样品存在两种类型的锆石:普遍发育变质增生边的碎屑锆石(剖面北段样品)和不发育变质增生边的典型岩浆成因的碎屑锆石(剖面南、中段样品)。前者显示2个年龄峰值(~2.5 Ga主峰、~2.0 Ga次峰),还形成了2473±24 Ma的上交点年龄和359±84 Ma的下交点年龄,而后者两个样品有着一致的年龄峰值(~2.0 Ga主峰、~2.5 Ga次峰和~1.39 Ga微小峰值)。3个样品的谐和年龄均大于1.3 Ga,并不能限定踏坡组的沉积时代,且均不支持其物源主要来自碧口岩群的传统认识。碎屑锆石地球化学判别图解指示它们的源岩主要为形成于造山带环境中的花岗岩类(花岗闪长岩和英云闪长岩)、基性岩和钾镁煌斑岩。基于样品中的岩屑类型,结合区域地质、古流向、锆石年龄对比和源岩判别,认为踏坡组的原始物源来自位于扬子板块北缘的太古宙—古元古代基底(鱼洞子杂岩和崆岭杂岩),并且鱼洞子杂岩在踏坡组沉积后期曾大面积出露/抬升。同时表明碧口地块可能至少在早中泥盆世就与扬子板块拼合在一起了。

Jiayu RONG,Yi WANG,Renbin ZHAN,Junxuan FAN,Bing HUANG,Peng TANG,Yue LI,Xiaole ZHANG,Rongchang WU,Guangxu WANG,Xin WEI[3](2019)在《Silurian integrative stratigraphy and timescale of China》文中认为Silurian is a period with the shortest duration in Phanerozoic except for the Neogene and Quaternary. It represents an important and unique interval when the biotic diversity recovered quickly after the end-Ordovician mass extinction, different paleoplates or terranes conjoined, big oceans disappeared or narrowed, climate and sea level changed frequently, global biotic provincialism became weaker, some primitive plants started to occupy the land. Silurian is also the first system of which all the chronostratigraphic stratotypes(i.e. the GSSPs) including four series and seven stages were established by the International Subcommission on Silurian Stratigraphy(ISSS). Nonetheless, during the post-GSSP studies conducted by ISSS in the middle1980 s, some Silurian GSSPs were found to have some congenital defects such as no index fossils available that hinder the high resolution subdivision and correlation on a regional or global scale. In this paper, based on the latest development of Silurian study in China, the progress in biostratigraphy, chronostratigraphy, event stratigraphy(such as facies differentiation, heterochrony of black shales, marine red beds, carbonate rocks and reefs), chemostratigraphy, and tectonic stratigraphy(e.g., widespread of the late Silurian rocks in South China and its tectonic implication) are systematically summarized. Some existing problems and the areas to be focused in future work are also discussed. It is suitable for chronostratigraphic study to concentrate not only on the boundary but also doing multidisciplinary analysis on the biotic, chemical, magnetic, environmental, and chronologic aspects, in order to enhance the reliability and the potential for regional and global correlation of a certain GSSP.Some important achievements are expected in these areas in the Silurian study in China:(1) ecostratigraphy and basin analysis of the Llandovery, and the correlation of integrative stratigraphy with a high resolution;(2) establishment of the Wenlock to Pridoli chronostratigraphic framework;(3) the chemo-and magnetic stratigraphy and the age of some key intervals and horizons;(4)further investigation on paleogeography and plate tectonics; and(5) origin and early evolution of the terrestrial ecosystem. Some new breakthroughs might occur in the restudy on some of those problematic GSSPs of some particular series and stages.

ZHENG Mianping,ZHANG Yongsheng,LIU Xifang,NIE Zhen,KONG Fanjing,QI Wen,Jia Qingxian,PU Linzhong,HOU Xianhua,WANG Hailei,ZHANG Zhen,KONG Weigang,LIN Yongjie[5](2016)在《Progress and Prospects of Salt Lake Research in China》文中提出China has unique salt lake resources, and they are distributed in the east of Eurasian salt lake subzone of the Northern Hemisphere Salt Lake Zone, mainly concentrated in the regions with modern mean annual precipitation lower than 500 mm. This paper preliminarily reviews the progress made in salt lake research in China for the past 60 years. In the research of Paleoclimate and paleoenvironment from salt lake sediments, a series of salts have been proposed to be indicators of paleoclimate, and have been well accepted by scholars. The chloride-sulfate depositional regions of the west Qaidam and the east Tarim have been revealed to be the drought center of China since the Quaternary, and more than 6 spreading stages of arid climate(salt forming) have been identified. Five pan-lake periods with highstands have been proved to exist during the late Quaternary on the Tibetan Plateau. In mineral resource prospecting and theories of the forming of salt deposits: the atlas(1:2500000) of hydrochemical zoning of salt lakes on the Tibetan Plateau has been compiled for the first time, revealing the zonal distribution and transition from carbonate type to chloride type from south to north and presenting corresponding mineral assemblages for different type of salt lakes; several large continental salt deposits have been discovered and the theory of continental potash deposition has been developed, including the salt deposition in deep basins surrounded by high mountains, the mineral deposition from multistage evolution through chains of moderate or shallow lakes with multilevels, the origin of potassium rich brines in gravel layers, and the forming of potassium deposits through the inheriting from ancient salt deposits, thus establishing the framework of "Continental Potash Deposition Theory"; several new types of Mg-borate deposits have been discovered, including the ulexite and pinnoite bed in Da Qaidam Lake, Qinghai, the pinnoite and kurnakovite bed in Chagcam Caka, Tibet, the kurnakovite bed in Lake Nyer, and the corresponding model of borate deposition from the cooling and dissolution of boron rich brines was proposed based on principles of geology, physics and chemistry. The anti-floatation-cold crystallization method developed independently has improved the capacity of KCl production to 3 million tons per year for the Qarham, serving the famous brand of potash fertilizer products. One 1.2 million ton K-sulfate production line, the biggest in the world, has been built in Lop Nor, and K-sulfate of about 1.6 million tons was produced in 2015. Supported by the new technology, i.e. brine preparation in winter-cooling-solarization-isolation-lithium deposition from salt gradient solar pond" the highest lithium production base at Zabuye Lake(4421 m), Tibet, has been established, which is the first lithium production base in China that reaches the year production of 5000 tons of lithium carbonate. The concept of Salt lake agriculture(Salt land agriculture) has been established based on the mass growth of Dunaliella and other bacillus-algae and the occurrence of various halophytes in saltmarsh and salt saline-alkali lands, finding a new way to increase arable lands and develop related green industry in salt rich environments. Finally this paper presents some new thoughts for the further research and development on salt science, and the further progress in salt science and technology will facilitate the maturing of the interdisciplinary science "Salinology".

CHEN Baoguo,ZHANG Jiuchen,YANG Mengmeng[6](2016)在《The Present Research and Prospect of Chinese Geosciences History》文中研究表明It has been over a hundred years since the birth of research on Chinese geosciences history, which was accompanied by the continuous progress of Chinese geosciences. For hundreds of years, it has grown out of nothing to brilliant performance by several generations of Chinese geologists committing their hearts and minds with the spirit of exert and strive without stop to promote the process of China’s industrialization and to produce the significant impact on serving the society. The study of Chinese geosciences history reflects objectively and historically the history of geosciences in China, which has recorded, analyzed and evaluated the dynamic process sitting in the background and clue of the history of Chinese geosciences development. The study of the history of geological science has roughly experienced two stages in China. The first stage is the study of individual researchers. It spanned approximately 70 years from the early 20th century to the end of the 1970s. The research contents were mainly based on the evolution of geological organizations, the development and utilization of individual mineral species, the history of deposit discovery and the research of geological characters. The main representatives are Zhang Hongzhao, Ding Wenjiang, Weng Wenhao and Li Siguang, Ye Liangfu, Huang Jiqing, Yang Zhongjian, Xie Jiarong, Gao Zhenxi, Wang Bingzhang and etc. The most prominent feature of this period is the accumulation of a very valuable document for the study of the history of China’s geological history and lays a foundation for the exchange of geological science between China and foreign countries. The second stage is organized group study. It took around 60 years from the 1920s to 1980s. It includes the history of Chinese geology, the history of geological organizations, the history of geological disciplines, the history of geological education, the history of geological philosophy, the history of Chinese and foreign geological science communication, the history of geologists and etc. The most chief feature of this stage is the birth of academic research institute―the establishment of the Commission on the History of Geology of the Geological Society of China.

WANG Chenghui,WANG Denghong,XU Jue,YING Lijuan,LIU Lijun,LIU Shanbao[8](2015)在《A Preliminary Review of Metallogenic Regularity of Gold Deposits in China》文中认为Gold is one of the most important mineral resources in China with its rich mineral resources. In recent years,significant progress has been made on the process of gold resource exploration. Some large and giant gold deposits were newly found and some important expansions in the main mining regions were also been completed. Studies on metallogenic regularity of gold deposits in China also have made achievements with a long–term work. This review aims to conclude the achievements of research on gold metallogenic regularity in China. Based on the data of about 2000 gold deposits and other ore(mineralized) occurrences,gold deposits in China were classified into five prediction types: gold deposits genetically related to granite–greenstone formation,gold deposits related to sedimentary formation(including the Carlin type and the metamorphosed clastic rock related vein gold deposit),gold deposits genetically related to volcanic rocks(including the continental and marine types),gold deposits genetically related to intrusions(including the porphyry type and the inner intrusion and contact zone related gold deposit),gold deposits of supergenesis(including fracture zone–altered rock gold deposit,placer gold deposit,gossan type gold deposit and soil type gold deposit). Statistics on precise chronology data of gold deposits indicate that there occurred 5 main periods of gold–mineralization in geological history of China. They were Neoarchean to Paleoproterozoic,Meso–Neoproterozoic,Paleozoic,Mesozoic,and Cenozoic. Gold deposits in China mainly formed in the Mesozoic and the Cenozoic. On the studies of the spatial–temporal distribution characteristics of gold deposits,53 gold–forming belts were delineated in China. The metallogenic regularity of gold deposits was preliminarily summarized and 71 gold metallogenic series were proposed in China. This suggests that it is necceary to deepen the study on metallogenic regularity of gold deposits and to provide the theory guide for the ore–prospecting for gold resources in China.

MAO Jianren1,LI Zilong2,ZHAO Xilin1,ZHOU Jie1,YE Haimin1,and ZENG Qitao3 1 Nanjing Institute of Mineral Resources,Nanjing 210016,China 2 Department of Earth Sciences,Zhejiang University,Hangzhou 310027,China 3 Department of Earth Sciences,Nanjing University,Nanjing 210093,China[9](2010)在《Geochemical characteristics,cooling history and mineralization significance of Zhangtiantang pluton in South Jiangxi Province,P.R. China》文中进行了进一步梳理The zircon SHRIMP dating of the Zhangtiantang granite gave an age of 159±7 Ma.,which shows that the granite was produced at the early Late Jurassic.The Ar-Ar plateau ages of biotite and K-feldspar from the Zhangtiantang pluton are 153.2±1.1 Ma and 135.8±1.2 Ma,respectively.The Ar-Ar anti-isochrone ages of biotite and K-feldspar are 152.5±1.7Ma and 135.4±2.7Ma,respectively.The ages represent the isotopic closure ages of minerals in the pluton.The Zhangtiantang granites are regarded as peraluminous crust-derived type granites to possess the typical geochemical characteristics of calc-alkaline rocks on continental margin,with enriched Si,K,Al(average value of A/CNK as 1.18),HREE,Rb,U,and Th,heavily depleted V,Cr,Co,Ni,Ti,Nb-Ta,Zr,Sr,P,and Ba,strongly negative Eu and common corundum normative(average value of C as 1.84).The εNd(t) values of the Zhangtiantang granite are-5.84 to-7.79,and t2DM values are 1.69 to 1.83 Ga,which indicates partial melting of continental-crust metamorphic sedimentary rocks during the Middle Proterozoic.The cooling history of the Zhangtiantang granitic pluton indicates that the cooling velocity of pluton was faster(about 67℃ /Ma) from zircon(158 Ma) to biotite(152 Ma),and was slower(about12℃ /Ma) from biotite(152.5 Ma) to K-feldspar(135.8 Ma).It can be deduced that the temporal gap(about 10 Ma) between the granite formmation and W-Sn mineralization in South China may be related to ordinary magma-hydrothermal processes by the variational cooling curve of the pluton.The Zhangtiantang pluton was formed in a compressive setting,with differentiation evolution and mineralization occurring in a relative relaxation setting.

唐一昂,赖健清,杨牧,梅嘉靖,刘启,吴剑,谌后成,郭兰萱,胡理芳,和秋姣[10](2017)在《广东韶关市一六钨矿床流体包裹体特征及成矿作用》文中进行了进一步梳理一六钨矿大地构造位置位于南岭成矿带中段南缘,粤北曲仁盆地西南缘,是粤北地区近年来重要的找矿勘查成果之一。矿床为典型的矽卡岩矿床,矿体赋存于上泥盆统帽子峰组矽卡岩以及NWW向钾长石-石英-白钨矿脉和云母石英脉中。通过野外观察和镜下研究,本文将成矿过程分为矽卡岩期(A)和热液期(B),矽卡岩期可以分为早期矽卡岩阶段(A1)、晚期矽卡岩阶段(A2)、钾长石英白钨矿阶段(A3),热液期可以分为云母石英脉阶段(B1)和石英碳酸盐阶段(B2)。矿区包含4种类型的包裹体:含子矿物三相包裹体(Ⅰ型)、气液两相水溶液包裹体(Ⅱ型)、CO2水溶液三相包裹体(Ⅲ型)、纯CO2包裹体(Ⅳ型),Ⅰ型包裹体仅见于A3阶段;Ⅱ型、Ⅲ型以及Ⅳ型包裹体在A3和B1阶段石英中均有发育,在A3和B1阶段白钨矿中还发育Ⅱ型包裹体。A3阶段Ⅰ型包裹体完全均一温度为162381℃,盐度为30.1%45.4%(wt%NaClequiv,下同省略),Ⅱ型包裹体完全均一温度为154363℃,盐度为1.49%11.0%,Ⅲ型包裹体完全均一温度为290390℃,盐度为2.20%6.88%;B1阶段Ⅱ型包裹体完全均一温度为152381℃,盐度为1.65%9.32%,Ⅲ型包裹体完全均一温度为281378℃,盐度为2.00%8.82%。激光拉曼探针分析表明,A3阶段和B1阶段流体中存在H2O、CO2、CH4和少量CO32-,指示流体处于还原的环境。包裹体完全均一温度—盐度关系图表明,数据点主要集中于三个区域:a区对应早期出溶成因的高盐度流体,b区反映流体发生了不混溶作用,c区反映早期高盐度流体与低盐度地下水混合特征。各区包裹体代表了岩浆期后残余原始流体不同阶段的演化产物。通过Ⅰ型包裹体计算得出的成矿压力范围为86.0415.8MPa,用Ⅱ、Ⅳ型包裹体对成矿压力进行校正得出,A3阶段成矿压力范围为86115MPa,成矿温度为176279℃;B1阶段成矿压力范围为5593 MPa,成矿温度为160228℃,估算成矿深度范围为3.624.26km。研究认为,流体在演化早期存在局部高压,流体不混溶作用要比外来流体混入更早发生,而流体混入促进了流体的不混溶作用。流体物理化学条件的改变、外来流体混入以及流体不混溶作用是引起钨矿沉淀的主要原因。
