黑龙江多宝山地区遥感找矿蚀变异常提取方法研究

Extraction Method of Alternation Anomaly Information Based on Remote Sensing Prospecting in the Duobaoshan,Heilongjiang

通过对遥感矿化蚀变异常提取方法的研究,总结出一套针对黑龙江省大兴安岭这类植被覆盖严重地区的矿化蚀变信息提取方法。采用比值分析和主成分分析相结合的方法提取了围岩的矿化蚀变信息,得到了大兴安岭多宝山地区的遥感异常蚀变信息图,并对蚀变异常提取结果进行了野外实地考察,证实了这种方法在该地区的可行性,为该区找矿提供了一定的依据。

This paper studies the method of alternation anomaly information based on remote sensing prospecting.It summarizes the method applicable for Daxing′an Mountain range,Heilongjiang,which is seriously covered by vegetation.In this paper,ratio and principle component analysis were used to extract the alternation anomaly information and the imagery of the remote sensed alternation anomaly result was obtained.Furthermore,the fieldwork was conducted to analyze the alternation anomaly result for confirming the feasibility of the method in the study area.The results can provide some basis for the prospecting in the area.
