Abstract: In this article, the backstripping technique was used in studying the subsidence characters of the Qiongdongnan (琼东南) basin (QDNB) in order to understand its dynamic mechanism of formation and evolution. Meanwhile, the geothermal characteristics of this area were summarized, and the stretching factors (β) of the upper crust, the whole crust, and the whole lithosphere were calculated. The QDNB is characterized by high subsidence rate, high geothermal gradient, high geothermal heat flow, and the lithosphere stretching and thinning of this area are depth dependent...
