摘要
喀拉玉尔滚构造带包括喀拉玉尔滚走滑断裂、北喀背斜、中喀背斜、南喀背斜及其次生构造。其中,北喀背斜、中喀背斜为塔北地区重要的背斜圈闭,同时也是塔里木油田的重点勘探对象。利用15 m空间分辨率的ETM+影像(多光谱和全色波段融合)及0.61 m空间分辨率的QuickBird影像构成的多空间分辨率遥感影像集,结合少量野外地质资料,成功地提取了北喀、中喀背斜上的25条次生小断裂,其后又运用里德尔单剪理论对新发现的小断裂性质进行了解释,最后利用ETM+影像确定了喀拉玉尔滚右旋走滑断裂的走向和位置,提出了对喀拉玉尔滚构造带的4点认识。
En echelon folds, North-Ka anticline, Mid-Ka anticline and South-Ka anticline, associated with Karayulgun strike-slip fault, are the most important hydrocarbon traps and thus are of great significance in exploration. In this paper, 25 secondary faults are successfully picked up by the use of multiple-spatial resolution remote sensing images combined 15 m spatial resolution ETM+ image (panchromatic and multi-spectral fusion image) with 0.61m spatial resolution QuickBird image and minor field material of geological work. It is found that their distribution fits with the Riedel simple shear pattern. It is believed that the direction and location of Karayulgun strike-slip fault can be decided by ETM+image.
