    摘要

  • 该数据集以Landsat-7 ETM+卫星数据为主要数据源，在已有地质矿产资料分析研究的基础上，采用计算机技术和GIS技术相结合的方法，完成了非洲地区约3020万km2面积的1:500万遥感地质解译。提取了地层、火山岩、中酸性侵入岩、基性岩或超基性岩、线性构造和环形构造等与成矿有密切关系的地质要素，划分出7个重要成矿带。形成了包含非洲地区Landsat-7 ETM+遥感影像图，非洲地区1:500万遥感地质解译图和非洲地区1:500万重要成矿带划分图在内的数据集，卫星数据分辨率为30 m，为在非洲地区开展基础地质研究和矿产勘查投资提供重要参考。

    Based on the analysis results of existing geological and mineral data and using computer technology and GIS technology, we completed a 1:5000000 remote sensing geological interpretation in Africa over an area of 30.2 million km2. The dataset used in this work takes Landsat-7 ETM+ data as its main resource. The geological elements, such as strata, volcanic rocks, intermediate acid intrusive rocks, basic or ultrabasic rocks, linear structures and ring structures which are closely related to mineralization were extracted, and seven important metallogenic belts were recognized. The dataset with the Landsat-7 ETM+ remote sensing image in Africa, the 1:5000000 remote sensing geological interpretation map in Africa and the 1:5000000 division map of important metallogenic belts in Africa were generated, the satellite data resolution is 30m, providing an important reference to carry out basic geological research and mineral exploration investment in Africa.
