摘要:
以内蒙古自治区西部阿拉善盟额济纳旗大狐狸山地区1:5万矿产远景调查为例,论述了遥感技术在1:5万矿产远景调查中的应用和具体工作方法。研究结果表明,在1:5万矿产远景调查中充分利用遥感技术,进行线性构造、环形构造、地质体的信息提取,利用主成分分析法有效提取矿化蚀变信息,在RGMAP数字平台,将工作区的标准影像图与其它数据源进行叠加整合,多轮回遥感地质解译成图,结合地质、物探、化探工作成果,快速有效地指导了地面找矿工作,对合理圈定找矿预测靶区起到了重要作用。
Abstract:
Taking the 1:50 000 minerals prospect investigation in Dahulishan area in western of Inner Mongolia as an example,we discuss the application and specific work method of remote sensing technique.The applications of remote sensing include information extraction of geological bodies,linear and circle structure,mineralization and alteration,and data extraction by the Principal Component Analysis,and remote sensing geological interpretation map by the superposition integration of standardimage with other data sources on the digital plat form of RGM AP.The results show that the full application of remote sensing technique in 1:50 000 mineral prospect investigation,combining with geology,geophysics and geochemistry,has been able to guide the work of prospecting quickly and efficiently on the ground,and has played an important role in selecting for ecasttarget area.
