目前,遥感图象的地质解译,应用于构造及工程地质等方面,效果比较显著,但用遥感手段找矿,效果则不甚理想.含矿岩系、与原生矿有关的围岩蚀变带、矿床露头及工业价值尚待查定的矿化点(本文对上述4种地质体统称为矿产信息)相对出露的范围皆小且不连续,在图象上一般仅分布在1个或数个象元点内.而且这些矿产信息与围岩之间,以象元点为单位的电磁波辐射能量的差异较小,反映在黑白图象上很少超过1个灰阶.由于上述原因,欲在1/100万黑白卫片上,目视解译矿产信息是完全不可能的.现阶段,国内外遥感
At present, the interpretation of geological images of remote sensing images is applied to tectonics and engineering geology, etc., and the effect is quite obvious, but the effect of prospecting by means of remote sensing is not very satisfactory.The ore-bearing rock series, the wall rock alteration related to the primary ore Belts, outcrops and industrial values of mineralization to be identified (in this paper, the above four kinds of geology are collectively referred to as mineral information) are relatively small and inconsistent range of exposure, the image is generally only distributed in one or Several pixel points, and these mineral information and the surrounding rock, in pixel unit as the unit of electromagnetic radiation energy difference is small, reflected in the black and white images rarely exceed 1 gray scale.Because of the above reasons, To 1/1000000 black and white tablets, visual interpretation of mineral information is completely impossible. At this stage, remote sensing at home and abroad
