- Abstract:
- Based on collection of focal mechanisms and in-situ stress measurements,we analyze the distribution feature of the stress field of the southern Tanlu fault and surrounding areas. Combined with the tectonic characters,we divided the study regions into three stress areas,i. e. the Tanlu fault west zone,the Subei rift zone and the Sunan uplift zone. Inverting the tectonic stress tensor of the three areas and analyzing the characters of each stress division,the results are as follows:(1)The west of Tanlu fault area and northern Jiangsu faulted area are extruded by the NEE stress in horizontal. The uplift area in the southern Jiangsu in horizontal is squeezing with the ～ EW stress.(2)The Tanlu west area is extruded in horizontal by the stress whose direction is between the NEE direction of the stress field in the northern Jiangsu and the ～ EW direction of the stress field in uplift area of southern Jiangsu.(3)The stress field in the east area of the Tanlu fault is controlled by the mechanism of normal fault with strike-slip component,and the stress field in the west area is controlled by the mechanism of normal strike-slip fault.(4)The direction of horizontal compressive stress in the entire study area distributes radially from west to east.
