【摘要】 遥感找矿信息是指遥感图像中与矿化有关的地质现象的信息。通常这些信息包括地质背景、控矿因素和岩石蚀变等。 笔者选择新疆维吾尔自治区库米什-依热大阪地区作为研究区，利用TM和ETM卫星图像数据，研究了该区与金属矿化有关的地质现象，并利用PCI7.0软件，在TM卫星图像上提取了矿化信息。 研究工作中，首先完成了TM图像的预处理工作；接着对已知矿(化)区(彩华沟地区)内与铜多金属矿化有关的地质现象进行了实地调查，确定了各地质现象在TM图像上的影像特征；然后对工作区图像进行了辐值统计分析、主成分分析等处理，提取了矿化信息；还有，把TM与ETM融合处理，获得了较高分辨率的图像，并依此图像为基础，进行了地质解译和分析，获取了地层-岩石单元和断裂构造单元的信息；最后，把获得的各种遥感信息与已知的地理、地质矿产等数据信息进行综合处理，建立了铜多金属遥感综合找矿预测模型，并进行了找矿预测。共圈定了找矿预测区4处，经野外检查，预测效果良好。更多还原

【Abstract】 Remote sensing ore-finding information is the information about geological phenomena related to mineralization in the remote sensing images. Usually, the information includes ore-forming geological background, ore control factors, rock alterations, etc.Selecting Ku Mi Shi-Yi Re Da Ban area of Sinkiang as research area based on the analysis of TM and ETM secondary planet image data about this area, the author studied the geological phenomena related to metal mineralization, and extracted mineralization information from the TM secondary planet images by using the software of PCI7.0.During the research, the TM image data were firstly pretreated. And the related to metal mineralization of the selected area(CaiHuaGou area)were investigated on the spot, the image-related features of various geological information contained in the TM image were defined. Then the statistics and analysis and principal analysis of the image data about the selected area were performed, the mineralization information contained in the images was extracted. Besides, the data-amalgamating processing of the TM and ETM images was performed, the images with higher degree of sophistication resolution were obtained. Based on these images, the interpretation and analysis of geological phenomena was performed, the information of stratum-rock units and fracture units was obtained. Finally, all the remote sensing information obtained together with the existing geographic data, geological and mineral data were synthetically processed, the copper-multimetal integrated remote sensing ore-finding forecast model was established, and ore-finding forecast was made,4 ore-finding forecast zones were confirmed, it shows that the forecast model is good after field examination.更多还原
