| 英文摘要 | Heat flow measurements and thermal history reconstruction, from inversion of apatite and vitrinite reflectance data, indicate that Bohai Basin is characterized by lower present-day heat flow varying between 50 and 75mW / m(2) with a background heat flow value of 63.6mW / m(2), and that the basin experienced a much higher heat flow (70-90mW / m(2)) period prior to about 25Ma. Structural subsidence analysis shows that the subsidence of Bohai Basin, consisted of East Liao Bay and Bohai areas, can be divided into two phases: earlier(25-50Ma) initial (rift) and later (since 25Ma) thermal subsidence. The earlier rift phase is composed of two sub-rift episodes with quick subsidence, and the later thermal subsidence was superimposed with rapid subsidence related to crustal isostasy induced by higher density mantle and cooling of the lithosphere. The lower present-day heat flow and the higher palaeo-heat flow corresponding to structural subsidence stage as well as the typical rift subsidence style in Bohai Basin support its feature of intraplate, rift basin, and provided with some insight to the tectonic-thermal evolution of the basin. |
