北巴颜喀拉山地区岩性遥感解译标志建立
发布时间：2018-11-06 12:23
【摘要】：岩性解译是遥感地质解译中十分重要的内容,解译前首先要根据待解译区地质体的岩性及其组合类型建立遥感解译标志。北巴颜喀拉山群复理石建造因岩性单一、地层厚度巨大、难见顶底且化石稀少,长期以来对该套地层的划分相对困难且争议颇多,形成了众多划分方案。针对这种情况,采用遥感方法,以SPOT5和ETM卫星遥感数据为基础影像,从岩性解译入手进行了最大程度的地质信息挖掘。从4个方面详细阐述了岩性解译和岩性组合划分的依据,系统地介绍了研究区基于遥感影像的岩性可视化解译标志的建立过程。并利用所建立的解译标志重新厘定了地层的影像特征,细分了各地层岩段或岩性组合,取得了对研究区地层岩性的新认识,为北巴颜喀拉山群地层对比及区域地质调查提供了新资料。
[Abstract]:Lithology interpretation is a very important content in remote sensing geological interpretation. Before interpretation, a remote sensing interpretation mark should be established according to the lithology and its combination types of geological bodies in the area to be interpreted. Because of its single lithology, huge formation thickness, hard to see top and bottom and few fossils, it has been difficult and controversial to divide this set of strata for a long time. In view of this situation, using remote sensing method and SPOT5 and ETM satellite remote sensing data as the basis image, the maximum degree of geological information mining is carried out from lithology interpretation. The basis of lithology interpretation and lithologic combination division are described in detail from four aspects, and the establishment process of lithology visual interpretation mark based on remote sensing image in the study area is systematically introduced. The image characteristics of the strata are redetermined by using the interpretation markers established, and the strata and rock formations or lithological assemblages are subdivided, and a new understanding of the stratigraphic lithology in the study area is obtained. It provides new data for stratigraphic correlation and regional geological survey of North Bayan Kara Mountain Group.
