摘要:

为了拓展遥感找矿技术在金找矿方面的应用,以内蒙古撰山子地区为例,选择Landsat 8 OLI遥感数据,在影像数据预处理的基础上,选取B7B5B3波段融合以增强区域构造信息,用主成分分析法通过阈值分割提取蚀变异常信息,结合区域地质特征和撰山子金矿床地质特征及遥感解译信息建立了撰山子地区金找矿标志,并圈定3处找矿预测远景区,经实地验证,找矿预测远景区存在金矿化,认为基于OLI遥感影像的线性构造、环形构造和遥感异常信息可作为金找矿预测的辅助手段。

Abstract:

In order to expand the application of remote sensing prospecting technology in gold prospecting,this paper takes the Zhuanshanzi area in Inner Mongolia as an example,and selects Landsat 8 OLI remote sensing data.On the basis of image data preprocessing,the regional tectonic information is enhanced by the fusion of B7B5B3 band.The principal component analysis is used to extract the alteration anomaly information through threshold segmentation.Based on the geological characteristics and remote sensing interpretation information of the region and Zhuanshanzi Gold Deposit,the prospecting indicator of gold deposits in Zhuanshanzi area is established,and 3 prospect areas for prospecting prediction are delineated.The field verification shows that there is gold mineralization in the prospect area.It is believed that the linear and ring structure and remote sensing anomaly information extraction based on OLI remote sensing images can be used as auxiliary means for gold prospecting prediction.
