It was said that mineral resources in oceans might be a reliable source for the material production. Ocean water is regarded as a huge “liquid deposit” for its ability to dissolve many kinds of elements. The total amount of elements in ocean water is greater than that in land. At the seafloor or below, occur a large number of mineral resources besides those in the water.China Sea, situated in the junction between North China block, Yangtze block and the Pacific plate and the Philippines plate, is excellent in ore-forming geological conditions, resulting in the presence of many kinds of deposits and abundant reserves. Mineral resources found in China Sea mainly include oil-gas resources, sea-beach placer and submarine coalfield.In addition, the manganese nodule and cobalt-rich crust are also discovered in South China Sea. Furthermore, the hydrothermal metalliferous deposit and gas hydrate may also be present in South China Sea. 相似文献

Identification and quantitative prediction of large and superlarge mineral deposits of solid mineral resources using the mineral resource prediction theory and method with comprehensive information is carried out nationwide in China at a scale of 1:5000000. Using deposit concentrated regions as the model units and concentrated mineralization anomaly regions as prediction units, the prediction is performed on GIS platform. The technical route and research method of locating large and superlarge mineral deposits and principle of compiling attribute table of independent variables and functional variables are proposed. Upon methodology study, the qualitative locating and quantitative predicting mineral deposits are carried out with quantitative theory Ⅲ and characteristic analysis, respectively, and the advatntage and disavantage of two methods are discussed. This research is significant for mineral resource prediction in ten provinces of western China. 相似文献

It is well known that the geophysical and geochemicalanomalies are very important for the location of mineral de-posits. However,the concept of geo-anomaly and its signifi-cance in mineral exploration had hardly been expounded until1 990 s.In fact,the geo-anomaly that has wider implicationsthan the geophysical and geochemical anomalies do,can bewidely applied to the assessment of mineral resources and theexplanation of some crucial geological phenomena. A geo-anomaly is defined as a geological… 相似文献

Long-term research on key techniques of clean utilization of potassic rocks from over twenty localities has been performed to settle the shortage of soluble potassium resources in China. The results show that K-feldspar as the principal mineral enriched in potassium could be decomposed in the media of Ca(OH)2, NaOH, KOH-H2O solution via hydrothermal treatment, into tobermorite, hydroxyl- cancrinite, and kalsilite respectively. By further processing, these compounds are feasible for being as slow-release carrier of potassium nitrate, extracting alumina, and preparing farm-oriented fertilizers of potassium sulphate and nitrate. Correspondingly, the filtrate is KOH, (Na, K)2SiO3, and K2SiO3 solution, from which potassium carbonate, sulphate, nitrate, and phosphate could be easily fabricated. As NaOH and KOH are recycled in the processing chains by causticizing sodium and/or potassium metasilicate solutions, the hydrothermal alkaline techniques as developed in this research have several advantages as lower consumption of disposable mineral resources and energy, maximized utilization of potassic mineral resources, as well as clean productions etc. Based on the approaches presented in this paper, the technical system of efficiently utilizing insoluble potassium resources has been established. The hydrothermal alkaline methods are feasible to be industrialized on a large scale, thus resulting in decreasing imports of potash fertilizers, improving the pattern of potassium fertilizer consumption, and enhancing the supplying guarantee of potassium resource in China. 相似文献

China is the third largest country in the world,with a land area of about 9.6 million km2.It is endowed with abundant mineral resources,and the metal mining activity can be traced back to ca.8000 years ago.However,due to language barrier,little has been known about the geology and tectonics to the outside world until 1980s.In the last three decades,a great deal of knowledge has been gained,enhanced by a vigorous cooperation between Chinese and Western geologists.Research papers about geological,geochemical,and geochronological features of mineral deposits of China are widely published and cited in international journals.A comprehensive and comprehensible English literature that summarises the features of mineral deposits in China,however,is still lacking. 相似文献

Owing to the internal relationship between material sources or mineralization ways and the difference ofmineralization micro-environments or the change of constraints. certain types of nonmetallic mineral depositsare regularly formed either simultaneously or in successive order under the control of certain association ofmineralization processes in a certain geotectonic environment, thus forming a minerogenetic series ofnonmetallic mineral deposits. The geological setting that controls the formation of minerogenetic series is mosttruly recorded in ore-bearing formations. while the mineralization processes which are associated or surely suc-cessive are the indispensable prerequisite for the formation of the various mineral deposits of a minerogeneticseries. Therefore, the minerogenetic series of nonmetallic mineral deposits can be classified according tomineral-bearing formations and mineralization processes. Based on available data. 13 minerogenetic series aredistinguished in China. The study of minerogenetic series may not only result in the enrichment of the theory ofmineral deposits but also help direct mineral prospecting and give guidance in the integrated development andutillization of mineral resources. 相似文献

Rare metals including Lithium (Li), Beryllium (Be), Rubidium (Rb), Cesium (Cs), Zirconium (Zr), Hafnium (Hf), Niobium (Nb), Tantalum (Ta), Tungsten (W) and Tin (Sn) are important critical mineral resources. In China, rare metal mineral deposits are spatially distributed mainly in the Altay and Southern Great Xingán Range regions in the Central Asian orogenic belt; in the Middle Qilian, South Qinling and East Qinling mountains regions in the Qilian–Qinling–Dabie orogenic belt; in the Western Sichuan and Bailongshan–Dahongliutan regions in the Kunlun–Songpan–Garze orogenic belt, and in the Northeastern Jiangxi, Northwestern Jiangxi, and Southern Hunan regions in South China. Major ore-forming epochs include Indosinian (mostly 200–240 Ma, in particular in western China) and the Yanshanian (mostly 120–160 Ma, in particular in South China). In addition, Bayan Obo, Inner Mongolia, northeastern China, with a complex formation history, hosts the largest REE and Nb deposits in China. There are six major rare metal mineral deposit types in China: Highly fractionated granite; Pegmatite; Alkaline granite; Carbonatite and alkaline rock; Volcanic; and Hydrothermal types. Two further types, namely the Leptynite type and Breccia pipe type, have recently been discovered in China, and are represented by the Yushishan Nb–Ta– (Zr–Hf–REE) and the Weilasituo Li–Rb–Sn–W–Zn–Pb deposits. Several most important controlling factors for rare metal mineral deposits are discussed, including geochemical behaviors and sources of the rare metals, highly evolved magmatic fractionation, and structural controls such as the metamorphic core complex setting, with a revised conceptual model for the latter. 相似文献

The tectonic development of the Tarim block has experienced four stages, i. e. Earth's core accretion and block formation in the Precambrian, margin splitting, opening-closing and piecing up in the Early Palaeozoic, rift formation and plate unification in the Late Palaeozoic, and basin-mountain coupling and landform shaping in the Meso-Cenozoic, forming six ore-bearing formations and ore deposits of various genetic types in the Tianshan Mountains, Kunlun Mountains and Altun Mountains. In the peripheral areas of Tarim there are four giant intercontinental metallogenic belts passing through, the Central Tianshan and southwestern Tianshan belts in the former USSR and the Qinling-Qilian-Kunlun and Palaeo-Tethys belts in China. According to the macro-analysis on the nearly one thousand known deposits (occurrences) and geophysical-geochemical anomalies, and the information from reconnaissance in some areas, the region has very good prospects for mineral resources. Some of the metallogenic belts may well becom 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

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
