ETM+遥感影像构造解译在找矿预测中的应用——以安徽钟姑山地区为例

Application of Remote Sensing ETM + Image in Structures Interpretation and Predication of Ore Prospecting——Setting Zhonggushan in Anhui Province as an Example

摘要:

安徽钟姑山地区位于扬子准地台下扬子台坳带宁芜火山岩盆地南段，属长江中下游铁矿成矿带，多以隐伏矿床为主。以陆地卫星遥感影像为基础通过遥感构造解译发现了一批新的隐伏断裂构造。通过遥感蚀变信息和地磁异常信息的叠置分析，共圈定A级预测区4个，B级预测区2个，C级预测区1个，为当前钟姑山铁矿资源勘查提供了有价值的新的依据。

Abstract:

Zhonggushan area in Anhui province locates in south section of Ningwu volcanic basin of Yangzizhun depression in the Yangzi platform. It belongs to ironforming belt of the lower reach of Changjiang river, and is mainly composed of hidden deposit. On the basis of satellite remote sensing image, through remoting sensing interpretation of structures, some new hidden faults have been found. At last, through remote sensing altered information and folding analysis of geomagnetic anomaly information, four predication areas with the level of A, two predication areas with the level of B, and one predication area with the level of C have been circled. It will provide valuable and new basis for iron ore resources exploration in Zhonggushan area.
