国产高分一号卫星数据在境外地质矿产调查中的应用——以伊朗法尔亚地区为例

The application of domestic GF-1 satellite data to geological and mineral resources survey abroad:A case study of Faryab area,Iran

近年来,国产卫星持续发展,无论从数据质量还是数量上都可以满足“一带一路”倡议对遥感地质调查工作的需求。主要利用国产高分一号卫星数据在伊朗南部铬铁矿富集地区开展不同尺度的遥感地质矿产解译工作,对研究区地质背景、成矿条件进行分析,并提出成矿有利地区。通过解译研究工作发现,Sorkband杂岩体北西侧的杂岩体中的层状超基性岩具有良好的铬铁矿找矿前景,同时也验证了国产高分一号数据在境外地质矿产调查工作中的良好应用效果,为基于国产卫星数据的境外地质矿产调查技术体系建立提供技术支撑,同时也为国内矿业企业的境外找矿工作提供一定的建议。

Recently,with the continuous development of domestic satellites,the quantity and the quality of remote sensing data have been improved observably,the needs of“Belt and Road initiative”in remote sensing geological investigation can be satisfied.In this paper,the authors carried out interpretation of geology and minerals in the southern part of Iran which is an area abundant of chromite based on GF-1 satellite data.The authors studied regional geological background and metallogenic condition and proposed the favorable areas for mineralization.Through the study of interpretation,it is found that the layered ultrabasic rocks in the northwest of Sorkband complex have a good prospect of chromite exploration,and it also verifies the good application effect of domestic GF-1 data in the overseas geological and mineral survey.This study is aimed at supporting the establishing of the system for domestic geological survey and making suggestions for mining enterprise.
