Using unmanned aerial vehicle oblique photogrammetry technology to obtain field outcrop image data and establish a three-dimensional model for observation, the NEE and NNW fractures are the most developed in the Yanchang Formation of the study area, while the NW and NNE fractures are slightly developed, all of which are high angle vertical fractures and belong to regional structural fractures. The NNW oriented cracks are restricted by the NEE oriented cracks and developed in the late stage. Combined with the analysis of regional geological background, fracture intersection relationship and tectonic stress field, it is considered that there are two stages of fractures in Dongjiahe, namely, the late Indosinian and Yanshanian.展开更多
