Abstract Recovery of denuded strata thickness is the foundation of making quantitative analysis of basin burial history,thermal history and hydrocarbon accumulation. In this paper,the denuded thickness of the Jurassic and Cretaceous in Yabrai Basin of Inner Mongolia was calculated by the methods of vitrinite reflectance(RO),fluid inclusion,interval transit-time and trend surface of formation thickness. The analysis results show that the total denuded thickness of the Jurassic and Cretaceous is 1610.9-2177.0,m, and that of Jurassic and Cretaceous is 930.2-1395.3,m and 0-612.1,m respectively under the constraint results calculated by fluid inclusion and trend surface of formation thickness methods. The denuded thickness of Jurassic appears larger in north and smaller in south, while that of Cretaceous shows diametrically opposed as larger in south and smaller in north. The spatial distribution characteristics of denuded strata thickness indicate that the intensity of tectonic uplift in north was much stronger than that in south during the Late Jurassic and interconverted during the Early Cretaceous. The formation temperature descended and the source rocks were destroyed after the large scale uplifting and denudation,and that restricted the maturity and thermal evolution of source rocks and even the hydrocarbon generation in Yabrai Basin to a certain extent.
