青藏高原地质矿产数据集（2021.11-2024.10）

青藏高原地质矿产数据库范围覆盖全区，数据内容包括地层、侵入体和构造信息，以及大宗金属矿产的种类、规模、空间分布和成因类型等信息，其中铜矿主要集中在冈底斯斑岩铜矿带和玉龙铜矿带，铅锌矿以念青唐古拉-北喜马拉雅热液脉型、矽卡岩型为主，受断裂和碳酸盐岩地层控制，铁和锰矿则多分布于羌塘-三江地区，以沉积- 平台，数据格式为 .GDB、MXD、JPG，也可根据需要导出 PDF、TIF、EPS 等格式的图件。基础地质数据主要基于域内各地质调查部门地质图（1:100万）；矿产数据主要来源包括全国矿产资源潜力评价项目成果（2012）、域内各地质调查部门相关资料数据、域内矿产相关论文论著。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。具体包括：①矢量化，基于前述资料进行了大量矢量化工作，按照我国相关规范要求比例尺精度要求下完成；②拓扑处理，消除重叠面、空区等拓扑错误；③完善。

The geological and mineral resources database of the Qinghai-Tibet Plateau covers the entire region. Its data contents include stratigraphic, intrusive body and structural information, as well as information on major metallic minerals such as their types, scales, spatial distributions and genetic types. Among them, copper deposits are mainly concentrated in the Gangdese Porphyry Copper Belt and the Yulong Copper Belt. Lead-zinc deposits are mainly of the Nyainqentanglha-North Himalayan hydrothermal vein type and skarn type, controlled by faults and carbonate strata. Iron and manganese deposits are mostly distributed in the Qiangtang-Sanjiang region, mainly of sedimentary-platform type. The available data formats include .GDB, MXD and JPG, and map files in formats such as PDF, TIF and EPS can also be exported as needed. The basic geological data is mainly sourced from 1:1,000,000-scale geological maps provided by various regional geological survey departments. The mineral data mainly comes from the results of the National Mineral Resource Potential Evaluation Project (2012), relevant data from various regional geological survey departments, and academic papers and monographs related to minerals in the region. Edits, processing and supplementary improvements have been carried out to ensure the spatial accuracy, logical consistency and data integrity of the dataset, specifically including: ① Vectorization: A large amount of vectorization work has been completed based on the aforementioned materials, meeting the scale accuracy requirements specified in relevant Chinese national standards; ② Topology processing: Eliminate topological errors such as overlapping surfaces and void areas; ③ Supplementary improvement.
