【Abstract】 Geophysical investigations have been carried out since 1996 for site-selection of Chinese Continental Scientific Drilling Project (CCSDP). The surveys mainly include deep seismic reflection and MT together with gravity and magnetic data, and the results are presented in this paper. An integrated interpretation of the geophysical data reveals crustal structures and main characteristics of the Dabie Sulu lithosphere. Good evidence for selecting the drilling site in Donghai County of southern Sulu is explained. Crustal structures and geothermal measurements around the drilling site are also discussed, with a comparison between the depth migrated seismic profile and core petrology at the CCSD pilot hole.更多还原
