云南锡矿遥感地质找矿模型

从云南锡矿床成矿地质环境、时空分布及矿床特征出发,将花岗岩的等级体制概念、控岩控矿构造的成矿构造体系概念和矿床展布的矿化单元等级体制概念引用到锡矿遥感地质模型研究中。根据丰富的锡矿地质科研资料与遥感图像的对应分析,发掘锡矿遥感影像-地质特征,进而拟建锡矿遥感地质找矿模型,即由赋锡总体特征模型、矿床定位最佳模型和影像-地质鉴别程序模型三部分组成的云南锡矿遥感地质找矿系列模型。

The Remote Sensing Geologic Prospecting Model for The Tin Deposits in Yunnan

Based on the fact that the essential factor of time-space distribution and metallognesis of Yunnan, tin deposits is tin-forming granite,and the granites and tin deposits are located by tectogenesis, the authors apply the tin metallogenic theory and the concepts of granite grade system, ore-forming structure system and the mineralization unit of deposits distribution to the research on the remote sensing geological model for tin deposits. Through the comprehensire analysis on remote sensing images, geology, ore deposits, geochemical and geophysical information of the tin mineraliztion concentrating area, the tinbearing remote sensing images are identified.Based on these images the author sum up the comprehensive imformation feature of remote sensing geology and the marks of tin-bearing remote sensing images. The romote sensing geological prospecting model has been setted.Taking the feature of remote sensing image as the trace of recognizing tin-bearing image,combining the image information with geologic environment,and carrying out the comprehensive identification of geoscientific information,all those are the important ways of recognizing the marks of tin-bearing images.The serial models of remote sensing geological prospecting for tin deposits in Yunnan involve the tin-bearing general feature model, deposit locating optimum model and image-geology identification program model.
