引言1977年底我们对(K-51)-7沈阳幅(象片编号114)5波段卫星象片进行了鞍本地区的地质解译,通过目视判读对该区的一些基本地质构造问题,如构造演化方向、基底构造轮廓、铁矿层的时代划分和展布规律等,从宏观上有了比较清楚的认识.然而,在卫星形象上各岩类的环境信息和岩类之间的界限,单用目视判读很难确立.为了提高在形象上分辨岩石的能力,增强岩类之间的界限,特别是了解在多波段遥感信息上各种铁矿石有无差异以及验证和补充目视解译结果,我们选取了鞍山地区的石英岩、铁矿石、千枚岩和片岩、花岗岩和混合岩四类岩石的23个样品进行了粉末样的可见一近红外(0.4～2.0μ)漫反射光谱测定.
Introduction By the end of 1977, we conducted a geological interpretation of a 5-band satellite imagery of (K-51) -7 Shenyang (No. 114) satellite imagery in the saddle area by visual interpretation of some of the basic geological formations in the area such as The direction of tectonic evolution, the outline of the basement structure, the age division and distribution of iron ore layers, etc. However, on the satellite image, the boundaries between environmental information and rock types of various rock types are relatively clear, In order to improve the ability to distinguish the image from the rock and to increase the boundaries between the rock types, in particular, whether there is any difference in various iron ores in the multi-band remote sensing information and to verify and supplement the visual As a result of the interpretation, we selected 23 samples of four types of rocks, quartzite, iron ore, phyllite and schist, and granite and mixed rock in Anshan area to conduct powder-like visible-near-infrared (0.4-2.0μ) Reflectance spectrometry.
