基于遥感技术的成矿预测方法和程序研究

The Method and Procedure of Metallogenic Prognosis Based on Remote Sensing Technology

基础地质和成矿理论研究是成矿预测的基础,成矿理论创新可大大拓宽成矿预测领域和找矿思路。遥感技术在控矿要素解译,成矿带展布研究,矿致色调异常、控矿环形影像、找矿地貌特征、矿化蚀变信息提取和多源信息综合分析等方面比常规找矿方法更具优势。根据在我国西部地区的找矿实践和效果,总结了一套遥感成矿预测方法和程序。

Remote sensing technology can play an important role in metallogenic prognosis. The study of foundational geology and ore - forming theory is the basis of metallogenic prognosis. The theoretical innovation of metallogenesis will expand the scope and direction of ore prediction, and can change the traditional prospecting thoughts. Remote sensing technology has much superiority over conventional geological investigation in such aspects as the ore - control factor interpretation, the extension of the mineralization belt, the tone anomaly caused by mineralization, the annular imagery controlled by mineralization, the geomorphic feature for prospecting, the mineralization information extraction and the comprehensive analysis of multi -source geoscience information. According to the results of ore prediction conducted in western China, this paper sums up a set of metallogenic prognosis methods and procedures based on remote sensing technology.
