【摘要】：論文以“西部重點成礦區(qū)帶高分遙感地質(zhì)礦產(chǎn)調(diào)查技術(shù)研發(fā)與應(yīng)用示范”項目為依托,在對沉積巖光譜特征充分認(rèn)識的基礎(chǔ)上,對庫拜盆地多光譜遙感數(shù)據(jù)(ETM+、ASTER)進(jìn)行了巖性-構(gòu)造信息增強(qiáng)并建立了巖性-構(gòu)造遙感解譯標(biāo)志,在此基礎(chǔ)上,對庫拜盆地巖性-構(gòu)造信息進(jìn)行提取�；趲彀菖璧貛r性-構(gòu)造信息提取結(jié)果并結(jié)合地質(zhì)資料,分析探討了庫拜盆地構(gòu)造演化特征。論文取得的主要成果如下:(1)在對沉積巖光譜特征充分認(rèn)識的基礎(chǔ)上,通過多種影像增強(qiáng)方法(基于色調(diào)的:波段組合法、對比度增強(qiáng)法、比值增強(qiáng)法、主成分變換法、HLS變換法;基于紋理的:高通濾波、定向濾波)對庫拜盆地多光譜遙感數(shù)據(jù)(ETM+、ASTER)進(jìn)行了巖性-構(gòu)造信息增強(qiáng)并取得了較好的增強(qiáng)效果。(2)在巖性-構(gòu)造信息增強(qiáng)的基礎(chǔ)上,建立了研究區(qū)巖性-構(gòu)造遙感解譯標(biāo)志,并結(jié)合高分辨率遙感影像(Google Earth、World View-2)的空間信息,對研究區(qū)進(jìn)行了巖性-構(gòu)造遙感解譯,查明了研究區(qū)內(nèi)巖性-構(gòu)造分布及其特點。(3)在對研究區(qū)巖性-構(gòu)造解譯基礎(chǔ)上,結(jié)合地質(zhì)資料,分析探討了庫拜盆地構(gòu)造演化特征,并根據(jù)遙感巖性-構(gòu)造解譯結(jié)果,從地層接觸關(guān)系、褶皺變形等角度分析,得出庫拜盆地新近紀(jì)以來經(jīng)歷了四期構(gòu)造變形作用,因而將庫拜盆地新近紀(jì)以來的構(gòu)造演化劃分為四個階段:前康村組演化階段、康村組—庫車組演化階段、庫車組-西域礫巖組演化階段、西域組-現(xiàn)今演化階段。
[Abstract]:Based on the project of "R & D and Application demonstration of High-score remote Sensing Geological and Mineral Survey Technology in West China's key metallogenic zones", and on the basis of fully understanding the spectral characteristics of sedimentary rocks. On the basis of the enhancement of lithology and structure information and the remote sensing interpretation of lithology and tectonics, the multispectral remote sensing data of Kuba Basin are presented. The lithology-structure information of Kuba basin is extracted. Based on the information of lithology-structure of Kuba basin, the information is extracted and combined with geological data. The main achievements of this paper are as follows: 1) on the basis of a full understanding of the spectral characteristics of sedimentary rocks. Several image enhancement methods (based on hue: band combination method, contrast enhancement method, ratio enhancement method, principal component transform method and HLS transform method) are used. Texture-based: high pass filtering, directional filtering) ETM for multispectral remote sensing data in Kuba Basin. ASTER2) based on the enhancement of lithology-structure information, a remote sensing interpretation mark of lithology-structure in the study area was established. Combined with the spatial information of Google Earth World View-2, the lithology and tectonics remote sensing interpretation of the study area was carried out. Based on the interpretation of lithology and structure in the study area and the geological data, the tectonic evolution characteristics of Kuba basin are analyzed and discussed. According to the interpretation results of remote sensing lithology and tectonics, from the angle of stratigraphic contact relationship and fold deformation, it is concluded that the Kuba basin has undergone four tectonic deformations since the Neogene. Therefore, the tectonic evolution of Kuba Basin since Neogene can be divided into four stages: Qiankangcun formation, Kangcun and Kuqa formation, Kuqa formation and Xiyu conglomerate formation. Western region formation-present evolutionary stage.
