西天山金矿遥感地质调查及重点地区金成矿条件研究

本文介绍了TM和SPOT等多源数据融合处理，以及提取蚀变影像信息和增强冻融带影像信息的方法。根据断裂构造（包括线性断裂、环状和弧形断裂构造）、地层、冻融带及蚀变带的解译，总结了西天山地区金矿成矿环境和成矿条件。在与邻区穆龙套、库姆托尔金矿对比研究的基础上，选定了重点研究地区，勾划了与金矿化关系密切的冻融带及构造蚀变带，为该区进一步开展金矿普查找和矿提供依据。

Remote sensing regional geologic investigation and research on gold metallogenic conditions in key prospective areas, western Tianshan, China

TM and SPOT data processing and multiple data fusion methods are discussed in this paper. Extraction and enhancement of alteration information and signature of freezing melting zone are also introduced in detail. According to image interpretation of fault structure (including linear fault, circular and arcuate faults), the strata, the freezing melting zone and the alteration zone in combination with field investigation, the gold metallogenic environment and conditions are summarized. Compared with Muruntau and Kumtor gold deposits in adjacent country, a key prospecting section has been selected. The freezing melting zones and structure alteration zones related to gold mineralization are delineated. The research results have laid a foundation for further gold reconnaissance in the studied area.
