Re-study on metallogenic mechanism and prospecting progress of Meika granite pegmatite deposit in western Sichuan. With the exploration breakthrough of "Strategic Study on Three Rare Resources in China" in the periphery of Meika Mining Area, Sichuan Province, the melt and sub-crystalline inclusions in granite and pegmatite in Meika Mining Area are emphatically analyzed. The composition and homogeneous behavior of inclusions indicate that the formation of the deposit is the product of liquid immiscibility of granite slurry, so it is determined that H2O-rich mica granite is the internal cause. Based on the prospecting model with high denudation degree and relatively closed and limited open environment, the prospecting criteria of methyl skarn deposits are summarized, which mainly include: relatively large metallogenic depth (about 14km), relatively closed tectonic environment (structure-metamorphic dome, silicon-aluminum surrounding rock and axis of compound anticline) coexisting with rock mass and cold shrinkage cracks of surrounding rock, and the ore-forming rock mass is mainly mica granite. According to this prospecting indicator, the prospecting prospect of West Sichuan-West Kunlun is analyzed. It is considered that Meika, Kerin and Dahongliutan deposits have the same metallogenic model and prospecting indicator, and the difference is only the degree of erosion. Suggestions: look for methyl card deposits in the periphery of Kerin, and increase the prospecting deployment in the southeast of Dahongliutan mining area; Looking for methyl card deposits in the tectonic-metamorphic dome areas around methyl card, such as Waduo, Changzheng and Ka Rong; In Meika mining area, according to the characteristics of metamorphic zoning and northward dip of mica granite, geophysical exploration of granite body was carried out in the north to find a new prospecting target area.

The formation of potassium in continental rift and the breakthrough of finding potassium in Jiangling. The global plate movement obviously controlled the evolution of supergene potassium, that is, from the Paleozoic stable craton basin and Mesozoic Tethys basin to the Cenozoic continental rift, that is, the mode of supergene potassium changed greatly, and the potassium in the basin was mainly replenished by seawater and became the main source in the basin. The theory of potassium formation in small fault basins is studied and put forward. Jiangling sag was selected for exploration and research, and 4 deep wells were implemented, and a large number of seismic interpretations were made. The predicted resource of potash controlled by the project was 200 million tons, and abundant associated resources such as boron, lithium, rubidium, cesium, bromine and iodine were obtained. Found the metallogenic indicator of solid potassium salt. The research on comprehensive development of potassium-rich brine shows that potassium and associated beneficial elements can be extracted. Now the pilot plant design has been completed and it is ready to enter the development stage.

Research progress on metallogenic regularity and metallogenic background in South China. South China is the most concentrated and representative area of Mesozoic mineralization in the world. Why so many metal elements accumulate and mineralize in a short time is an important scientific issue that scientists all over the world pay attention to. This study has determined that there are three large-scale metallogenic peaks in Mesozoic in South China, namely, 230 ~ 265, 438+000 Ma, 65, 438+070 ~ 65, 438+037 Ma and 65, 438+035 ~ 80 Ma, and their spatial distribution characteristics are the east-west continental plate, the middle part of Qinhang-Nanling, the middle and lower reaches of the Yangtze River and the continental margin. The corresponding metallogenic backgrounds are post-collision, oblique subduction and compression and post-subduction and extension. It is found that the minerals formed in 135 ~ 80ma are developed in extensional basins on the continental margin. It is pointed out that the copper polymetallic metallogenic belt in Qinhang and the middle and lower reaches of the Yangtze River is closely related to the tearing of the Izanamu plate along the paleotectonic unit during subduction. It is considered that the copper belt in the middle and lower reaches of the Yangtze River and the tungsten belt in the south of the Yangtze River are the products of the same tectonic event, and it is preliminarily revealed that the regional metallogenic zoning in South China discovered by Mr. Weng in the 1920s was the result of a composite mineralization in the middle and late Jurassic.

Research results of national important minerals and regional metallogenic regularity: complete the research report of national important minerals and regional metallogenic regularity 1 copy, work report 1 copy, and complete the summary research report of 16 national single minerals (ore groups); There are 64 series maps and 4 maps in 4 categories, such as the national single mineral metallogenic regularity map. 16 sub-mineral databases and 1 summary databases have been established, and the project tasks and objectives have been fully completed. The research puts forward the unified technical requirements for the study of important minerals and regional metallogenic laws in China, which effectively guides the study of provincial metallogenic laws; It is the first time to realize the full coverage of grade I, II, III and IV metallogenic belts; In this paper, 23 classification schemes of mineral prediction types are put forward and 388 types of mineral prediction are determined. Based on the study of 17 single mineral, the metallogenic belt of single mineral is divided for the first time. The metallogenic regularity of 17 metallogenic belt is systematically studied, the regional metallogenic model and regional metallogenic pedigree of each metallogenic belt are perfected, and the prospecting potential is analyzed, which provides scientific basis for mineral prediction and exploration work deployment. The list of metallogenic models of typical deposits, the field survey atlas of typical deposits and the compilation of isotopic age data of diagenetic mineralization 1 1886 are compiled, which provides scientific basis for mineral prediction and exploration evaluation. There are important innovations in the study of regional metallogenic regularity, such as the new metallogenic model of "five-layer basement", Mesozoic magmatic mineralization in South China, the symmetry of magmatic mineralization on the north and south sides of North China Plate and Junggar Plate, and the large-scale distribution of nickel deposits. The multi-stage mineralization of gold, antimony and mercury deposits in the "low-temperature metallogenic domain" of Guizhou and Hunan, and the spatial relationship between large deformation structures such as arc-mountain spiral broom structure and minerals in China are put forward, which is of great significance to the development and discussion of metallogenic theory. A group of young backbones and 19 doctors and postdocs have been trained, and 10 monographs and 168 papers have been published. The results of the work not only directly applied to the mineral prediction of the proposed project, but also played an effective guiding role in the exploration and evaluation of important deposits such as Dachang tin polymetallic deposit in Guangxi, Taoxikeng tungsten deposit in Jiangxi, Pangushan tungsten deposit and Dazhuyuan bauxite deposit in Guizhou, and achieved good prospecting results.
