摘要

摘要: 选取我国重要矿集区内蒙古帮帮乃别力切尔地区作为研究区, 提出一种改进后的遥感蚀变信息提取方法, 即先分区提取蚀变信息, 后引入地形校正的提取方法。首先按照地貌、地形、岩性对研究区进行分区, 对提取的蚀变信息进行地形校正, 再综合地质资料以及物化探资料, 对研究区进行矿化蚀变信息综合提取, 并进行成矿预测。该方法较传统方法更好地显示了矿物蚀变信息, 消除了地形、岩性对异常信息提取的影响, 为今后的找矿勘查提供了更为准确的依据。

Abstract: This article selects Bangbangnaibeiiiqieer that is located in China's major ore concentration area in Inner Mongolia as the research area and proposes an enhanced extraction of alteration information using remote sensing, which extracts alteration information first, and then uses topographic correcting. Firstly, the area is divided according to landform, topography and rock character, and then the extracted alteration information is corrected based on topography; Secondly, alteration information is extracted combing geological data, geophysical prospecting data and geochemical exploration data. Finally, metallogenic prediction is built. This new study is better than previous study, because it can display alteration information obviously, eliminate the effects of topography and rock character, and offer a more accurate evidence for further mineral investigation.
