摘要
通过对阳高地区已知金矿点的研究 ,指出该区金矿的物质来源、成因类型以及不同级别断裂对金矿形成的控制作用。利用遥感图象处理技术 ,在假彩色合成及比值假彩色合成图象上提取与金矿成矿有关的构造、围岩蚀变信息等 ,并在 TM图象上解译出大量环形构造 ,将所获得的多种信息进行复合。结合该区部分物探、化探资料 ,确定了圈定该区成矿远景区的原则 ,在区内圈定了孙仁堡、水磨口、朱家沟 3个成矿远景区 。
Through studying the known gold ore spots in Yanggao region,the source of ore forming material,genetic types and controlling factors of different level faults are indicated. Using remote sensing image process technology, the information of structure and wall rock alterations related to the gold deposit is put forward on the basis of false color composite and ratio color composite, and many ring structures are interpretated on the TM images.The obtained information is composited.Combining some data about geophysical and geochemical exploration, three prospect areas of Sunrenpu,Shuimokou,and Zhujiagou are decided.This paper provides the reliable basis for further ore prospecting.
