青藏高原东南缘构造演化与成矿区划图

青藏高原东南缘构造演化与成矿区划数据库范围覆盖青藏高原南缘，内容涵盖区内成矿域、成矿省、成矿带的空间划分和完善的构造相（陆块大相、弧盆系大相、结合带大相）划分，以及各类断层、构造相界线和成矿带界线，大宗金属矿产的种类、规模、空间分布和成因类型等信息。其中成矿域为羌塘-三江成矿域、冈底斯-喜马拉雅成矿域；成矿省为三江成矿省、冈底斯-念青唐古拉成矿省。矿产以铜、铅锌为主，铜矿主要集中在印支运动时期，建造组合为弧后盆地和被动陆源槽硅质-陆生岩石、硅质-粘土-碳质岩石、粘土-碳质岩石组合；铅锌矿主要集中在印支运动时期，建造组合为双峰式裂谷火山沉积岩组合。基础地质数据（构造相、成矿区带、断层）主要基于成都中心的青藏高原地质图、青藏高原构造图、云南省地质志；矿产数据主要源于云南省矿产志、全国矿产资源潜力评价项目成果（2012）、矿产相关论文论著。在数据空间准确性、逻辑一致性和数据完整性方面进行编辑、处理以及补充完善。包括：①矢量化，基于前述资料按我国相关规范要求的比例尺精度进行矢量化工作；②拓扑处理，消除拓扑错误；③完善要素属性结构和要素属性内容；④结合青藏高原研究成果和认识，对空间数据进行了持续修改和完善。主要服务于青藏高原南缘构造演化与成矿区划图（1:100万）编制，综合数据库内容和区域构造演化与成矿动力学分析。

The Tectonic Evolution and Metallogenic Regionalization Database of the Southeastern Margin of the Tibetan Plateau covers the southern margin of the Tibetan Plateau. Its contents include the spatial division of metallogenic domains, metallogenic provinces and metallogenic belts in the region, as well as the refined division of tectonic facies (large-scale continental block facies, large-scale arc-basin system facies, large-scale suture zone facies), together with information on various faults, tectonic facies boundaries, metallogenic belt boundaries, and the types, scales, spatial distributions and genetic types of bulk metal mineral resources. The metallogenic domains include the Qiangtang-Sanjiang Metallogenic Domain and the Gangdese-Himalayan Metallogenic Domain; the metallogenic provinces include the Sanjiang Metallogenic Province and the Gangdese-Nyainqentanglha Metallogenic Province. The dominant minerals are copper and lead-zinc. Copper deposits are mainly concentrated during the Indosinian orogeny, with their host rock assemblages being back-arc basin and passive continental trough siliceous-terrestrial rocks, siliceous-clay-carbonaceous rocks, and clay-carbonaceous rock assemblages. Lead-zinc deposits are also mainly concentrated during the Indosinian orogeny, with their host rock assemblage being bimodal rift volcanic-sedimentary assemblage. Basic geological data (tectonic facies, metallogenic zones and faults) are mainly derived from the Tibetan Plateau Geological Map, Tibetan Plateau Tectonic Map and Geological Record of Yunnan Province from the Chengdu Center. Mineral resource data mainly come from the Mineral Record of Yunnan Province, the achievements of the National Mineral Resource Potential Evaluation Project (2012), and relevant papers and monographs on mineral resources. Edits, processing and supplementary improvements have been carried out to ensure the spatial accuracy, logical consistency and data integrity of the database, including: ① Vectorization: Vectorization work was conducted based on the aforementioned materials in accordance with the scale accuracy required by relevant Chinese specifications; ② Topology processing: Topological errors were eliminated; ③ Improvement of feature attribute structures and attribute contents; ④ Continuous modification and improvement of spatial data based on research achievements and understandings of the Tibetan Plateau. This database is primarily developed for the compilation of the 1:1,000,000 scale Tectonic Evolution and Metallogenic Regionalization Map of the Southern Margin of the Tibetan Plateau, as well as for comprehensive database-based regional tectonic evolution and metallogenic dynamic analysis.
