摘要：This article discusses the Meso-Cenozoic thermal history, thermal lithospheric thinning, and thermal structure of the lithosphere of the Bohai Bay Basin, North China. The present-day thermal regime of the basin features an average heat flow of 64.5 +/- 8.1mW m(-2), a lithospheric thickness of 76-102km, and a 'hot mantle but cold crust'-type lithospheric thermal structure. The Meso-Cenozoic thermal history experienced two heat flow peaks in the late Early Cretaceous and in the middle to late Palaeogene, with heat flow values of 82-86mW m(-2) and 81-88mW m(-2), respectively. Corresponding to these peaks, the thermal lithosphere experienced two thinning stages during the Cretaceous and Palaeogene, reaching a minimum thickness of 43-61km. The lithospheric thermal structure transformed from the 'hot crust but cold mantle' type in the Triassic-Jurassic to the 'cold crust but hot mantle' type in the Cretaceous-Cenozoic, according to the ratio of mantle to surface heat flow (q(m)/q(s)). The research on the thermal history and lithospheric thermal structure of sedimentary basins can effectively reveal the thermal regime at depth in the sedimentary basins and provide significance for the study of the basin dynamics during the Meso-Cenozoic.
