Abstract

Fracture characteristics in Rudong Yangkou area, Jiangsu province have been studied through various geophysical methods combined with geothermal drilling data in this paper. Results indicate that there are three fault systems in Yangkou area, including a NW-trending secondary fault system of Binhai fault, EW-trending Benchahe fault system and Haian-Hekou fault. The NW-trending secondary fault system contains four secondary faults, mainly distributed in the north of Yangkou area and Laobagang area. The faults are steeply NE-dipping, with dip angles range from 70° to 80°, and speculatively cut through the Neogene strata. The EW-trending Benchahe fault system contains three secondary faults, mainly distributed in the middle of Yangkou area. The faults are mainly north dipping, with dip angles range from 60° to 80°. Combined with previous seismogeological and geothermal data in Yangkou area, it is comprehensively speculated that Benchahe fault is active, which makes the Quaternary Holocene strata being cut off with minor displacement. The activity of Benchahe fault influences the safety in the construction and development of Yangkou Economic area. The EW-trending Haian-Hekou fault is south dipping with the dip angle about 70°, extending from haian to the south of Yangkou area and cut off the Paleogene strata. There is compatible corresponding relation between distribution characteristics of faults and geothermal resources in Yangkou area, which is of certain guiding significance for the geothermal resources exploitation in this region.
