| 中文摘要:青海省成矿条件优越，矿产资源丰富，是我国矿产资源的主要蕴藏地之一。围绕“总结百年勘查成果和成矿规律”的宗旨，通过《中国矿产地质志?青海卷》研编统一的技术要求，系统梳理核实了青海省共发现矿产种类有137种，发现各类矿产地2587处，基本反映了青海目前的矿产资源现状。青海省成矿作用多样，以岩浆作用、沉积作用为主，含矿流体作用、变质作用次之，表生作用较弱。 探讨了大地构造格局、演化与成矿作用；深化了典型矿床和成矿规律研究，取得了一些创新性成果。系统编制了新一代矿产地分布图、矿产地质图和成矿规律图，展示了矿产资源空间上划分为秦祁昆成矿域和特提斯成矿域两大成矿域，涉及5个成矿省、16个成矿带；经历了前南华纪、南华纪—泥盆纪、石炭纪—三叠纪、侏罗纪—白垩纪、古近纪—第四纪五个时段的演化。发展了“成矿系列”理论，共厘定矿床成矿系列48个，亚系列114个，建立完善了青海成矿体系框架。成果应用服务于青海柴达木盆地北缘稀有金属找矿、柴达木盆地深层含钾卤水找矿突破、东昆仑贵金属、稀有金属找等地区促进形成一批战略性矿产勘查基地。 依据以上，研判了青海省矿产资源潜力和找矿前景，提出了新一轮找矿突破战略行动，勘查部署中柴达木盆地聚焦盐湖增产保供、东昆仑突出战略性矿产找矿、共和盆地、贵德盆地实现新能源矿产找矿新发现。为实施国家能源资源安全战略提供基础支撑。 |

| 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 |

| Abstract: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. |
