Based on ZY-3 high resolution satellite image and digital elevation model (DEM), the authors obtained volcanic geomorphology features in Aershan volcanic region by means of satellite image interpretation, the relief degree of surface and surficial-slope analysis. According to the results of the study, 19 Quaternary volcanos were found. They could be divided into five categories. The landforms can be divided into four classes according to relief degree of surface. Low position middle mountain is the main type (39.61%), followed by low position low mountain (36.24%). 80% of the long axis direction of the elliptical volcanic cones are ranging from 45° to 75° with a median value of 58.5°. It is parallel to the NE-trending volcanic chain of Xiaodonggou volcano-Shihaogou basin volcano-Yanshan-Gaoshan. The horseshoe-shaped craters are in the direction of NE, SW and NW. The median difference between NE and SW horseshoe-shaped craters is about 180°. The NW horseshoe craters are almost parallel to NW faults. The authors predict that there are NE faults controlling volcanic eruption and distribution. Thereby an inference can be drawn that the NE-trending fractured zones were controlled by Mesozoic basement faults in the study area, and provided the channel for magma to approach. Fracture controlled the magma ascending and the formation of NE-trending volcanic apparatus, and eventually affected the distribution of volcanic cones and morphology.
