内蒙古朱拉扎嘎地区成矿遥感信息提取及成矿预测研究
Researches on metallogenic remote sensing information extraction and metallogenic prediction in Zhulazhaga area of Inner Mongolia
摘要
Abstract
With ETM+ data as the information source, the authors made a detailed study of the ore- forming geological characteristics and the remote sensing features of the Zhulazhaga gold deposit, which is a typical ore deposit. Ore bodies occur in the first member of Agulugou Formation of Zhaertaishan Group, which is composed of calcium -bearing shallow metamorphic clastic rocks. The linear structure information was extracted by visual comprehensive interpretation method, the information of abnormal alteration of iron stain and hydroxyl related to mineralization was extracted by principal component analysis, and the abnormal alteration was optimized by using spectral angle method. An overlay analysis of information by GIS technology has determined the ore-prospecting criteria for copper-gold deposits: (1) the first member of Agulugou Formation of Zhaertaishan Group; (2) the well-developed linear structure; (3) the existence and overlay of abnormal alteration of iron stain and hydroxyl; (4) Strong geochemical anomalies and well-consistent concentrated centers. Six prospecting target areas in this area, such as northern lateral and western lateral of Zhulazhaga, were delineated by using the ore -prospecting criteria.关键词
