关 键 词：Southern South Yellow Sea Basin heat flow thermal history thermo-tectonic evolution 

摘      要：Based on the available borehole temperature data and measurements of thermal conductivities on 10 core samples in the Southern South Yellow Sea Basin,8 heat flow values are *** results show that the mean values of temperature gradient and heat flow are 28.6℃/km and 69 mW/m,*** thermal history reconstruction from the inversion of vitrinite reflectance data,using the temperature-gradient method,indicates that the highest paleo-heat flow occurred at the end of the Mesozoic,and then the basin began to cool to present *** subsidence analysis shows that the basin experienced at least four episodes of quick subsidence since the late Paleozoic and that the tectonic evolution was quite strong and complex.
