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. 相似文献

Copper resources in China are rich, but imported copper products are still required. Researches on metallogenic regularity of major types of copper deposits by geologists have involved in worldwide classification, significant copper belts, representative copper deposits, etc. Studies on metallogenic regularity of copper deposits in China also have made achievements with a long-term work. Combined with latest exploration advances obtained in recent ten years, this review aims to conclude the achievements of researches on copper metallogenic regularity in China. Based on data of 814 copper deposits and other ore (mineralized) occurrences, ten prediction types of copper deposits have been suggested. Porphyry and skarn copper ores are taken as the key targets. Porphyry copper deposits are the most important one which concentrate in Gangdese, Changdu-Sanjiang, Dexing and East Tianshan. The Cenozoic and Mesozoic are the major metallogenic epochs. Four main metallogenic epochs are been studied based on the copper ore geochronological data including Precambrian Era (Archean and Proterozoic), Paleozoic Era, Mesozoic Era and Cenozoic Era. Based on the study of metallogenic series of ore deposits in China, twenty-seven metallogenic series of copper deposits are proposed. This is suggested to deepen the study of metallogenic regularity of copper ore and provide the theory guide for copper resources prediction in China. 相似文献

China is rich in tin resources,and contains many types of tin deposits.Among the tin deposit types,the cassiterite-sulfide type,skarn type and quartz vein type occupy a large proportion of tin resources and reserves.From the aspect of exploitation and utilization,the most important types are cassiterite-sulfide type and quartz vein type.The cassiterite-sulfide type tin deposits are mainly located in Northern Guangxi and Eastern Yunnan,skarn type deposits are mainly distributed in the ore-concentration areas of South Hunan in Middle Nanling,and the quartz vein type tin deposits are mainly distributed in South China,such as Western Fujian,Middle Jiangxi,Northern Guangzhou and Southern Hunan.The most important metallogenic epoch for tin deposits is the Mesozoic era.The metallogenic geotectonic background is mainly continental environments after orogeny process,with strong tectonic changes,interlaced deep fracture and frequent magmatism.And the most distinctive feature is the well developed Mesozoic granites,which have a close relationship with tin mineralization.Based on the detailed study of the data from 873 tin deposits in China,this paper summarized the metallogenic regularity of tin deposits,classified 20 important metallogenic series of tin or tin-associated deposits,and inferred that the cassiterite-sulfide type,skarn type,quartz vein type and greisen type are the main prediction types of tin resources.Forty-four tin-mineralization belts were divided,among which,19 belts are the most important.In addition,a series of maps about tin metallogenic belts and tin metallogenic regularity were compiled,aiming to provide theoretical basis for potential estimation and prediction of tin mineral resources. 相似文献

China has widely distributed silver deposits,and is rich in silver resources.Although silver deposits are mainly associated with Pb-Zn deposits,a number of independent silver deposits have also been discovered in recent years.Silver deposits include different types,such as submarine volcanism and continental volcanism related type,intrusion related type,and sedimentary related type.This study summarized the metallogenic regularity of China’s silver deposits systematically based mainly on the data from 490 silver deposits.It is shown that submarine volcanic sedimentary type,continental volcanic or sub-volcanic type,skarn type,hydrothermal type(including vein type and stratabound type),sedimentary metamorphic type,sedimentary type and regolith type should be regarded as the most important prediction types of silver deposit.A total of 32 silver mineralization belts and 111 silver concentration areas have been delineated.The map of "Spatial distribution of silver mineralization belts in China" and other series of maps finished in this study may provide a theoretical basis for the evaluation and prognosis of silver resources potential in China. 相似文献

Tungsten ore resources are abundant in China with relatively complete types of deposits. Skarn type and quartz vein type deposits are dominated in the tungsten resources, whereas quartz vein type wolframite deposits are most important in terms of exploitation and utilization. Skarn type tungsten deposits are concentratedly distributed in the central Nanling region, such as South Hunan, South Anhui and the eastern Qinling region, while quartz vein type tungsten deposits occur mainly in South China, such as West Fujian, South Jiangxi, North Guangdong and South Hunan. The most important metallogenic epoch of tungsten is the Mesozoic, while the metallogenic tectonic setting is featured by an intracontinental environment after orogeny with sever tectonic movements, deep-seated faults and frequent magmatic activities, especially Mesozoic granitoids closely related to tungsten-tin mineralization. 22 metallogenic series of ore deposits characterized by or significantly related to tungsten were defined based on precise statistic information of 1199 tungsten mining areas and thorough the summary of metallogenic regularities. Based on studies of the metallogenic regularity of tungsten deposits, skarn type (or greisen type), quartz vein type and massif-type of tungsten deposits are thought to be the key prediction types. 65 tungsten-forming belts and 22 key ore concentration areas were ascertained and a distribution map of tungsten-forming belts of China was compiled, which provided a theoretical basis for evaluation and prediction of potential tungsten resources. 相似文献

The important strategic metal cobalt has diverse uses and the majority of world cobalt deposits have been found in China. The deposits can be classified into four types, i.e., magmatic Ni-Cu-Co sulfide deposits, hydrothermal and volcanogenic cobalt polymetallic deposits, strata-bound Cu-Co deposits hosted by sedimentary rocks and lateritic Ni-Co deposits, of which the former two types are the most important. There are six principal metallogenic epochs and seven important metallogenic belts according to their distribution and tectonic position. Although cobalt generally occurs in nickel-copper, copper and iron deposits as an associated metal, great developments in exploration for independent cobalt deposits have happened in China, and, in recent years, many independent deposits with different elementary assemblages and different genetic types have been discovered in the eastern part of the northern margin of the North China platform, the Central Orogenic Belt of China, western Jiangxi and northeastern Hun 相似文献

The Daiyunshan-Shiniushan volcanic depression in Fujian Province is situated in a volcanic belt of the southeast coastal area in China along the west Pacific Ocean. A new breakthrough has been made in the exploration of gold and silver ore deposits in recent years. The minerogenic series of the Daiyunshan-Shiniushan volcanic depression is discussed in this paper based on the analysis of major metallogenic types and factors. According to the study of enormous ore deposits and occurrences in the study area, two minerogenic series have been recognized: 1. Late Jurassic Au-Ag-Pb-Zn minerogenic series related to intermediate-acid, acid volcanic formations; 2. nonmetallic minerogenic series (pyrophyllite, alunite pearlite, andalusite, zeolite, corundum and so on) related to intermediate and acid volcanic formations. The division and study of the minerogenic series have revealed metallogenic and time-space distribution characteristics of the ore deposits in the volcanic belt of the southeast coastal area in Ch 相似文献

Assessment of Prospecting Potentiality for Superlarge Continental Volcanic Rock—Type Uranium Deposits in China 总被引：1，自引：0，他引：1
The superlarge continental volcanic rock-type uranium deposits,which were discovered abroad long ago,have not ye been reported up to now in China.This is an important problem that needs to be urgently solved by uranium geologists at present.In this paper,on the basis of analyzing the metallogenic settings and geological conditions of the superlarge continental volcanic rock-type uranium deposits discovered in the world along with the metallogenic characteristics of those of the same type in China,the space-time distribution patterns of continental volcanics and the metallogenic potential of main tectono-volcanic belts in China are discussed,and a synthetic conclusion has been drawn that there is a possibility to discover the superlarge continental volcanic rock-type uranium deposits in China.Moreover,it is evidenced that the Ganhang,Nanling,Yanliao,Da Hinggan Ling and other tectono-volcanic belts possess favorable geological conditions for the formation of ssuperlarge ore deposits of the continental volcanic rock type.The intersecting and overlapping locations of the aforementioned main belts with other tectono-volcanic(-intrusive)belts are the most potential areas where the superlarge continental volcanic rock-type uranium deposits would be found. 相似文献

Current Gold Prospecting in China 总被引：1，自引：1，他引：0
In China, there are 12 types of gold deposits in 57 class-III metallogenic zones, formed in 7 main metallogenic periods. Most gold deposits are small or occur as ore spots; very large deposits are rare with relatively poor quality, mainly medium to low grade. Only 35% of the total gold reserves is identified, while a large amount of reserves is yet to be identified. In recent years, China Geological Survey has organized or conducted mineral resources survey and evaluation project, replacement resources prospecting for deposits in crisis, old mines prospecting and commercial prospecting funded or encouraged by the Central Government. These efforts have been fruitful. According to the temporal and spatial allocation of gold resources, and experiences from recent prospecting efforts, western China and the deep layers and peripheries of the-sits in eastern China have relatively high prospecting potential. The government should give even more support to the gold industry and strengthen technological innovation to help address difficulties in gold exploitation and processing. The government should also formulate consistent plans, consolidate mining rights, and promote integrated exploration, so as to achieve new major breakthroughs in gold prospecting. Gold is both a form of material wealth and a way of storing wealth. It is a rare resource with dual functions of commodity and currency. As an important global strategic asset and a cornerstone of financial reserves, gold plays an irreplaceable role in securing national economic development, maintaining financial security, strengthening national comprehensive power and promoting RMB internationalization. Based on latest research and prospecting results, the thesis proposes preliminary conclusions on types, temporal and spatial allocation, and exploration and development of gold deposits in China; predicts China’s gold resource potential; reviews recent gold prospecting and exploration efforts; and, in the hope of offering some reference for the new round of gold prospecting, exploration and planning, offers some suggestions. 相似文献

粤北地区产铀岩体的铀矿化特征及其成矿机制探讨 总被引：7，自引：0，他引：7
粤北地区是中国花岗岩型铀矿最为重要的大型矿聚集区,其主要的产铀花岗岩体是诸广山岩体和贵东岩体,均为多期多阶段的复式岩体,主要以印支期和燕山期的花岗岩为主。粤北地区的铀矿床主要由诸广山的长江铀矿田、澜河铀矿田、鹿井铀矿田和贵东岩体的下庄铀矿田组成,根据铀的成矿特征可分为硅化带型、交点型和碱交代型。粤北地区的铀成矿流体主要来自于地幔,而不是以往认为的花岗岩浆期后热液,铀源主要是粤北产铀岩体的印支期花岗岩。因此在华南开展新一轮铀矿找矿时,跳出以往“沿带找矿”的老思路,聚焦于印支期岩浆作用与铀矿床的关系,并重点关注华南地区可能的地幔柱或热点区域。 相似文献
