【摘要】：本文通过区域地质背景分析与卫星影像解析,建立了岩性、地层、产状、褶皱和断层发育的影像判识模型,结合野外地质勘察校验与构造变形特征分析,对徐州大北望地区的地质构造进行了研究。研究表明:卫星影像解析对碳酸盐岩地区的岩性、产状和构造均具有很好的判识程度,利于快捷准确地开展地质调查工作,为野外地质工作研究提供了新思路。根据地形地貌、岩层露头、"V"字形法则、地层分布、褶皱和断层识别标志在卫星影像中的响应特征,建立了岩性、地层、产状、褶皱和断层发育的影像判识模型,并对大北望地区进行了构造识别和野外地质校验。大北望地区地质构造较为发育,NE向直立水平家后山背斜构造整体控制该区的地层分布和地形地貌特征,大型NE向纵向和斜交逆断层的发育造成局部地层缺失,NW向和NWW向斜向平移断层的发育造成了局部地层错移和山谷发育。
[Abstract]:Based on regional geological background analysis and satellite image analysis, an image recognition model of lithology, strata, occurrence, fold and fault development is established in this paper, combined with field geological survey verification and structural deformation characteristics analysis. The geological structure of Dabei Wang area in Xuzhou is studied. The results show that the satellite image analysis has a good recognition degree for the lithology, occurrence and structure of carbonate rock area, which is helpful to carry out the geological survey quickly and accurately, and provides a new way for the field geological work research. According to the response characteristics of landform, rock outcrop, "V" zigzag rule, stratigraphic distribution, fold and fault identification mark in satellite image, the image recognition model of lithology, formation, occurrence, fold and fault development is established. Structural identification and field geological verification are also carried out in Dabeiwang area. The geological structure in Dabiwang area is relatively developed. The NE vertical level Houshan anticline structure controls the stratigraphic distribution and topographic features of the area. The development of large NE vertical and oblique reverse faults resulted in local stratigraphic absence and the development of NW and NWW syncline translation faults, which resulted in local strata dislocation and valley development.
