| 英文摘要 | Based on available borehole temperature logging and thermal conductivity measurement of core samples in the northeastern Sichuan Basin, we have estimated 12 terrestrial heat flow values. The results show that the present-day geothermal gradients ranges from 18 to 25 degrees C/km, with an average of 21 degrees C/km, and that the present-day heat flow varies from 41 to 57 mW/m(2), with a mean of 49 mW/m(2). Thermal history reconstruction in the northeastern Sichuan basin using vitrinite reflectance data indicates that the paleo-heat flow reached the maximum values (62 similar to 70 mW/m(2)) around 255Ma, and then decreased till present. The maximum erosion occurred on the Mesozoic-Cenozoic unconformity and reached similar to 2100 m. The abnormal high pressure in the area was formed under geotemperature background characterized by low paleo-heat flow. |
