航空高光谱遥感技术在雪鞍山地区找矿中的应用
|
摘要
为了推进找矿突破,利用CASI/SASI航空高光谱遥感数据,对雪鞍山地区进行了航空高光谱测量,修正了部分线性构造及环形构造。基于航空高光谱遥感提取的蚀变信息,结合野外实地调查验证,重点分析了研究区内矽卡岩型铁(铜)矿床、热液脉型金(铜)矿床与构造、蚀变之间的关系,结合已有的矿床地质特征、航空高光谱遥感地质特征,针对不同的矿床类型,构建了研究区矽卡岩型和热液脉型矿床的航空高光谱遥感找矿模型,并圈定6处找矿有利地段和3处找矿靶区,研究成果为其他地区的成矿预测与同类型矿床的勘查提供了遥感依据。
To advance prospecting breakthrough,the paper conducted aerial hyperspectral measurement in Xueanshan area based on CASI/SASI aerial hyperspectral remote sensing data and corrected part of the linear and ringed structures. Based on the alteration information extracted from aerial hyperspectral remote sensing and verification by outdoor field investigation,the paper analyzed the association tectonics and alteration have with skarn-type iron( copper) deposit and hydrothermal vein-type gold( copper) deposit,established aerial hyperspectral remote sensing model for skarn-type and hydrothermal vein-type deposit prospecting according to different deposit types based on known deposit geological features and aerial hyperspectral remote sensing geological features,and delineated 6 favorable spots and 3 prospecting targets. The research achievements provide remote sensing basis for the prospecting work of similar deposits and metallogenic prediction in other areas.
