The comprehensive study of China metallogenic system belongs to the project of land and resources survey. The unit in charge of the project is the Institute of Mineral Resources of Chinese Academy of Geological Sciences, and the participating units are Tianjin Institute of Geology and Mineral Resources and Chang 'an University. Main completion personnel: Chen Yuchuan, Wang, Shen Baofeng, Tang Zhongli, Chen, etc. Relying on the project of "China Metallogenic System and Regional Metallogenic Evaluation", this project has enriched the content of metallogenic series and improved the understanding of metallogenic system and metallogenic law in China through in-depth study of mineralization and metallogenic series. According to the new data, the grade I, II and III metallogenic belts in China have been re-divided, and the division of metallogenic belts in the sea area has been increased, thus realizing the full coverage of the country for the first time. This paper puts forward the inevitability, contingency, generality and particularity, reality and possibility of "all-position mineralization-ore-free prospecting" from the perspective of materialist dialectics, so as to reveal the metallogenic law, guide geological prospecting, embody the basic idea of predicting "possibility" with "reality" and have great significance for expanding the prospecting ideas. On the basis of in-depth study of major basic geological problems such as geological tectonic environment of metallogenic system in major geological historical periods, the Precambrian metallogenic system in China, the Paleozoic plate tectonic metallogenic system and the Mesozoic-Cenozoic continental metallogenic system were further established, which fully reflected the respective essence and characteristics of the four major metallogenic systems in China. A digital and systematic expert system of China metallogenic system has been explored and preliminarily constructed, which provides convenient query service for geological and mineral exploration and basic research of mineral geology. From 20 10 to 1, the project passed the acceptance of the evaluation Committee of the results report of China Geological Survey with excellent results.
Study on metallogenic conditions and prospecting criteria of volcanic sedimentary boron deposits in Qinghai-Tibet Plateau: It belongs to a survey of land and resources, and its main members are Zheng Mianping,, Li Jinsuo,, Yuan,, Cao Jianke,, Liu Danyang,. Through years of in-depth investigation of the research area, the project has achieved the following main results.
It is found and confirmed that there is a boron-rich volcanic sedimentary rock series with binary structure in Qinghai-Tibet Plateau, and its age is 2 1 ~ 16ma measured by K-Ar and SHRIMP. Its metallogenic age is the same as the main boron-forming belt in Anatolia, Turkey. The positive anomalies of boron, lithium, cesium, rubidium and arsenic in the dual structure of volcanic deposits are found for the first time, which are equivalent to those in the volcanic sedimentary rock series of Anatolia. ulexite and borax minerals are found in volcanic sedimentary rocks, and some boron minerals have reached industrial grade. Multi-disciplinary studies such as remote sensing, hydrochemistry, rocks and minerals fully reveal that there is a large range of geochemical high abundance of boron and lithium (rubidium and cesium) in Kahu area, and its positive and abnormal areas are about 10000km2. Through the study of regional geology and petrology, the geological and structural background of the formation of early Miocene volcanic sedimentary rocks in Sekazhi was found out. This area is located near the edge of the Anatolian plate. Kahu boron-rich ultrapotassic volcanic sedimentary rock series was formed in the background of India plate and closed fault basin extending east and west in Eurasia after the continental-continental collision, and boron (lithium) substance may be the product of partial melting of lithosphere and mantle. Investigation shows that the thickness of borax and ulexite produced by modern Kahu Lake is greater than 1m, and it is found that boron or lithium in 10 modern salt lake and saltwater lake reach industrial grade. It is preliminarily estimated that the resources of B2O3 and LiCl are 8.3 million tons and 46,000 tons respectively. It is pointed out that the Qinghai-Tibet Plateau belongs to the middle section of the Hoh Xil-Qinghai-Tibet Railway and was deposited in the early Miocene (Wudaoliang Formation and Chabaoma Formation), which is worth exploring volcanic sedimentary boron deposits. The investigation results show that the volcanic deposit boron mineralization area in Kahu area of Tibet has the structural geology, rock minerals and geochemical conditions of volcanic deposit boron, and has the potential to find super-large volcanic deposit boron. This achievement is a pioneering achievement of breaking through the super-large volcanic sedimentary boron deposit in China, which provides an important scientific basis for finding this type of deposit in the Qinghai-Tibet Plateau.
Study on the operational mechanism of strategic mineral exploration in China: It belongs to the geological survey project of China Geological Survey, and the main personnel are: Wang Ruijiang, Cui Yanhe, Wang Wen, Luo Xiaoling, Sun Yan, Zhang Xinan, Li Jianwu, Yan Shiqiang and Liu Shuchen. Guided by Scientific Outlook on Development, the project deeply analyzes the domestic and international environment and situation faced by mineral exploration in China. The basic connotation, nature orientation, main tasks and deployment principles of strategic mineral exploration are expounded in detail. This paper systematically analyzes the changes and characteristics of China's mineral exploration management system, and evaluates the achievements and existing problems of China's geological work system and operation mechanism during the planned economy and socialist market economy. Comprehensively collect the basic data of mineral exploration management system and operation mechanism in countries with market economy system as the main body in the world, and make comparative analysis and research from the aspects of industry management system, mineral exploration investment, mineral exploration subject and mining right operation in combination with China's actual characteristics, and put forward the basic elements of constructing mineral exploration operation mechanism suitable for China's socialist market economy system and suggestions for the next step of reform. This paper expounds and analyzes in detail the operation mechanism of strategic mineral exploration in China, such as market access and exit, work deployment, prospecting incentive, scientific and technological guidance, subject interaction, risk exploration, investment and financing, quality control, exploration benefit distribution, mineral strategic reserve and data public service. Some important problems in China's strategic mineral exploration are discussed, such as the construction of public welfare geological team, the guiding and pulling effect of national public welfare geological work on commercial mineral exploration, and "going out". These understandings and suggestions have important reference significance for promoting China's strategic mineral exploration.
Study on reflection seismic detection of porphyritic iron-sulfur deposits and ore-controlling structures: high-resolution reflection seismic has incomparable advantages in detection depth and resolution compared with other methods. In order to test the effectiveness of this method in detecting deep "layered" deposits and ore-controlling structures, supported by the national special plan for crisis mines, in 2008, Lu Qingtian's research team collected two high-resolution reflection seismic profiles of 10km in Luohe-Nihe-Dabaozhuang mining area in Luzong (Lujiang-Zongyang) ore concentration area of Anhui Province. Although the structure of the mining area is very complex, many reflections are still found on the superimposed profile: the clear reflection characteristics of the Cretaceous sedimentary red basin reveal that the red basin has a three-layer structure with a thickness of about 1200m. According to the analysis of sedimentary rhythm, under the background of extensional structure since Cretaceous, the extensional speed and sedimentary environment in this area have changed in stages. The volcanic rock layer has a three-layer structure, and the thickness of volcanic sedimentary rocks (Shuangmiao Formation and Zhuanqiao Formation) is about 800 ~1000 m. There is obvious "dome" reflection under the volcanic sedimentary rocks, and it is inferred that there may be a "nose" uplift intrusion. Compared with the established geological profile, there are clear reflections above the Luohe ore body and the Nihe ore body, which basically correspond to the position of the ore body, and it is preliminarily confirmed that the ore body can be directly detected by high-resolution reflection earthquake. At the same time, it is also found that when the ore body is steep, or the structural shape is complex, or the spatial size is small, the corresponding ore body has no reflection or scattered weak reflection. The test results show that under appropriate conditions, high-resolution reflection seismic can be used to detect deep ore-controlling structures and layered ore bodies.

Searching for potassium in Saskatchewan: a social project, mainly completed by Wen Qi, Zheng Mianping, Yan Changming,,, Huangshi. The Institute of Mineral Resources and Zhongchuan International Mining Holdings Co., Ltd. have carried out strategic cooperation to search for potassium around the potash mineralization belt in Saskatchewan, Canada. Through a large number of seismic geophysical prospecting, drilling coring, test analysis and comprehensive geological research, a large-scale high-quality potash deposit was discovered in KP488 block. The potash mine is located at the top of Middle Devonian, and there are three potash mines in * * * *, with the buried depth of 1229 ~ 1308m, the average thickness of 19.25m, and the ore body area controlled by drilling is 37km2. The ore type is potassium chloride with an average grade of 32.8%. KCl resources are huge, reaching 502,558,500 tons, including: controlled internal economic resources (3.32) KCl 33,308,400 tons, inferred internal economic resources (3.33) KC146,925,438+0,000 tons. Exploration shows that this is a large-scale high-quality potash deposit with good development prospects.

Study on metallogenic conditions of porphyry copper deposits around Junggar Basin in Xinjiang: It belongs to the geological survey project of China Geological Survey, and was completed by Yang Fuquan, Yan Shenghao, Liu Yulin, Zhou Gang, Liu Dequan, Wang Yitian, Yang Jianmin and Song Huixia. The report divides the metallogenic age of porphyry copper deposits in Junggar, Xinjiang into four periods, namely, Late Silurian-Devonian (427 ~ 4 1 1 Ma), mainly distributed in Qiongheba area of East Junggar. Middle Devonian (378 ~ 376 Ma), mainly distributed in Karaxiangger area on the northern margin of Junggar; Carboniferous (327 ~ 296 Ma), mainly distributed in Xilekuduk in the northern margin of Junggar and Baogutu in western Junggar; Triassic, mainly seen in Xilekete Halasu copper mine, superimposed on the mineralization of Middle Devonian. The Junggar porphyry metallogenic belt in Xinjiang shows a new metallogenic era from east to west, from 427 ~ 465,438+08ma (Tonghualing copper mine) → 465,438+065,438+0ma (Mengqian copper-molybdenum mine) → 374 ~ 378ma (Xileke Harasu copper mine and Yuleken Harasu copper mine) →327Ma (copper mine). Many large and super-large deposits have been discovered in the east and west of the country. Therefore, Junggar, which is in the middle transition zone, also has the conditions to form large and super-large deposits. This paper systematically studies the Baogutu porphyry copper deposit, establishes the diagenetic and metallogenic chronology of the Baogutu porphyry copper deposit, and discusses the mineralization. The metallogenic age of Halasu porphyry copper deposit is determined, the properties and sources of ore-forming fluids are studied, and the deposit model is established. It is pointed out that the early mineralization occurred in the Middle Devonian and was related to porphyry. The late superimposed mineralization occurred in the middle-late Triassic, which was related to the tectonic-magmatic-hydrothermal activity.
