资源简介:
本数据库包含空间范围:中亚四国(哈萨克斯坦、吉尔吉斯斯坦、塔吉克斯坦、乌兹别克斯坦)。数据内容主要有:中亚四国构造相数据集(岩石建造组合、构造分区、成矿区带、远景区、靶区、矿产);图件包括:中亚四国地质矿产图(1:150万)。空间数据库采用ArcGIS平台,可为区域成矿规律研究、资源潜力评估、战略远景区圈定以及各类专题图件编制提供基础数据支撑。数据库格式为文件数据库(GDB),图件包括工程文件(MXD)和栅格图(JPG),也可根据需要生成各类常见图形格式(PDF、TIF、EPS等)。中亚四国构造相数据采用兰伯特等形圆锥投影,中央经线为东经75度,双纬分别为35度和62度。为满足各类数据修改及完善大量采用遥感数据,具体包括:ETM+、OLI、ASTER、Worldview等影像数据以及90m、30米、12.5mDEM数据等。数据质量描述;为满足泛第三极区域成矿规律研究、地质矿产图和成矿预测图编制需要,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,用于补充数字资料缺失区域(伊朗、巴基斯坦),同时根据资料更新程度合并、分割各类面要素和线要素,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完善要素属性结构和补充要素属性内容,围绕区域成矿规律研究、地质矿产图和成矿预测图编制目标,依据我国相关规范,结合具体资料和数据内容,建立了相应数据模型,完善了地质体、构造、矿产要素类属性结构并完成了相应属性的填写工作;④基于以上数据处理内容,结合泛第三极研究成果和最新认识,对区内相关地质内容进行了进一步修改和完善。数据应用成果及前景:数据库主要服务于中亚四国(哈萨克斯坦、吉尔吉斯斯坦、塔吉克斯坦、乌兹别克斯坦)、以及其成矿规律研究、构造相图编制,比例尺为1:150万(中亚四国)。

This database covers four Central Asian countries: Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan. The main data contents include the tectonic facies dataset for the four Central Asian countries, which covers rock assemblages, tectonic divisions, metallogenic belts, prospective areas, target areas, and mineral deposits; the included maps are the 1:1,500,000-scale geological and mineral map of the four Central Asian countries. This spatial database is developed based on the ArcGIS platform, and can provide basic data support for regional metallogenic regularity research, resource potential assessment, strategic prospective area delineation, and the compilation of various thematic maps. The database is stored as a File Geodatabase (GDB). The included map files consist of ArcGIS project files (MXD) and raster maps (JPG), and various common graphic formats (PDF, TIF, EPS, etc.) can also be generated as needed. The tectonic facies data of the four Central Asian countries adopts the Lambert Conformal Conic Projection, with the central meridian at 75°E and the two standard parallels at 35°N and 62°N respectively. To meet the needs of data modification and improvement, a large amount of remote sensing data has been adopted, including ETM+, OLI, ASTER, Worldview and other image data, as well as 90m, 30m, and 12.5m DEM data, etc. Data Quality Description: To meet the requirements of metallogenic regularity research in the Pan-Third Pole region, and the compilation of geological and mineral maps as well as metallogenic prediction maps, edits, processing and supplementary improvements have been carried out in terms of data spatial accuracy, logical consistency and data integrity. The details are as follows: 1. Vectorization: A large number of vectorization tasks have been carried out based on the aforementioned data to supplement the areas lacking digital materials (Iran and Pakistan). Meanwhile, various polygon and line features are merged or split according to the update status of the data. The vectorization work is completed in accordance with the scale accuracy requirements specified in relevant Chinese standards. 2. Topology processing: Topological errors such as overlapping polygons and empty areas have been eliminated. 3. Attribute structure improvement and content supplementation: A corresponding data model has been established based on relevant Chinese specifications, combined with specific materials and data contents, targeting regional metallogenic regularity research, and the compilation of geological and mineral maps and metallogenic prediction maps. The attribute structures of geological body, tectonic and mineral deposit feature classes have been improved, and the corresponding attribute information has been filled in completely. 4. Further revision and improvement: Based on the above data processing contents, combined with the research results and latest understanding of the Pan-Third Pole region, relevant geological contents within the study area have been further revised and improved. Data Application Achievements and Prospects: This database mainly serves the four Central Asian countries (Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan), supporting their regional metallogenic regularity research and tectonic facies map compilation, with a map scale of 1:1,500,000 for the four Central Asian countries.
