| Metallogenic regularity, past century mineral exploration results and a new round of prospecting breakthrough suggestions in Qinghai Province——Research and compilation of “Geology of Mineral Resources in China |
| Qinghai Province is one of the main reserves of mineral resources in China. It has superior metallogenic conditions and abundant mineral resources. Focusing on the purpose of "summarizing the mineral exploration results and metallogenic regularity of the past century", through the unified technical requirements of the Research and compilation of “Geology of Mineral Resources in China (Qinghai Volume)”. A total of 137 kinds of minerals and 2,587 mineral deposits were found in Qinghai Province, which basically reflects the current status of mineral resources in Qinghai Province. There are various mineralization processes in Qinghai Province, mainly magmatism and sedimentation, followed by mineralizing?fluid?process and metamorphism, and relatively weak supergenesis.?The tectonic framework, evolution and mineralization were discussed.??The research on typical deposits and metallogenic regularity had been deepened, and some innovative achievements have been made.?The new generation of mineral deposits distribution map, mineral geology map and metallogenic regularity map are systematically compiled, they show that the mineral resources are spatially divided into two metallogenic regions: Qin-Qi-Kun metallogenic domain and Tethys metallogenic domain, involving 5 metallogenic provinces and 16 metallogenic belts.??These metallogenic domains had experienced five periods of evolution: Pre-Nanhua Nanhua - Devonian, Carboniferous - Triassic, Jurassic - Cretaceous and Paleogene - Quaternary.?The theory of "metallogenic series" was developed, 48 metallogenic series and 114 sub-series were determined, and the metallogenic system framework of Qinghai was established and perfected. The results have been applied in rare metals prospecting in the north margin of Qaidam Basin, breakthrough in deep potassium-bearing brine prospecting in Qaidam Basin, and precious metals and rare metals prospecting in East Kunlun.??They promoted the formation of a number of strategic mineral exploration bases. Based on the above, the mineral resources potential and prospecting prospects of Qinghai Province were studied and judged, and a new round of prospecting breakthrough strategic action was proposed, focusing on salt lake production and supply in the central Qaidam Basin, highlighting strategic mineral prospecting in East Kunlun, and realizing new energy mineral prospecting in Gonghe Basin and Guide Basin.??It will provide basic support for the implementation of the national energy and resources security strategy. |
