西昆仑北部地区铅锌铜矿带遥感构造蚀变信息提取与成矿预测

论文摘要

根据遥感异常信息提取的需要,在西昆仑北部地区的典型矿区——铁克里克-卡兰古铅锌铜矿带采集地表蚀变岩石样品,应用短波红外矿物分析技术对其矿物组合进行波谱分析,以ASTER和ETM+数据为基础提取矿化蚀变信息;同时通过图像增强等多种数据处理方法提取研究区的线性构造及环形构造,得到研究区1:100000的遥感异常图。从已知矿点在空间的分布情况看出,西昆仑北部地区铅锌铜矿带不但受地层层位的明显控制,构造控矿作用也十分明显。因此,结合矿化蚀变强烈程度、地层层位和该区赋矿层位吻合情况、构造活动强烈程度等综合情况,圈定出一级成矿预测区3个,二级成矿预测区4个。更多还原

【Abstract】 The Pb-Zn-Cu ore belts in the northern part of West Kunlun are important Pb-Zn ore belts in China.They are located in the Tiekelike-Kalangu area,inbetween the southwest of Tarim Basin and west Kunlun orogen.The deposits occurring in the belt are controlled obviously by the Devonian terrestrial clastic sedimentary and Carboniferous carbonate sediments.We investigated the correlation between mineralization distribution and the fault system through remote sensing image interpretation on the alterat... 更多还原
