密度分层组合成技术是通过对遥感图象密度层次的分折,以突出影象的结构信息为主的一种光孚图象处理方法。根据不同密度层次的多波段遥感图象具有不同类别结构的“信息丰度”的原理,通过对分层片的组合处理,比较成功地对影象信息进行增强和提取,从而获得较好的地质解译效果。实践表明,它不仅对构造解译是有效的,而且对地层、岩性解译也是可行的。在矿床、矿田构造解译力面,它可以获得一些以前没有被认识的信息。本文是基于对我国某铀矿田的卫片进行密度分层处理和解译,提出了矿田受菱形断裂构造块体控制的看法。它对认识铀矿田的构造特点,指导找矿是有一定意义的。
Density layering technology is a kind of optical image processing method which focuses on the structure information of the image through the analysis of the density of the remote sensing image. According to the principle of “information abundance” of multi-band remote sensing images of different density levels with different categories of structure, the image information is enhanced and extracted successfully by the combination processing of layered slices to obtain better geological Interpretation of the effect. Practice shows that it is not only effective for tectonic interpretation, but also feasible for interpretation of strata and lithology. In the deposit, ore field structure interpretation, it can get some previously unknown information. This article is based on the density of a piece of uranium ore field in our country stratified treatment and interpretation, put forward the view of the mine controlled by the diamond-shaped fault block. It is of certain significance to understand the tectonic features of uranium orefields and guide mineral prospecting.
