A valid method to study paleogeotemperature

摘要

The kerogen samples from three basins were tested by Electron Spin Resonance method. Based on the Tertiary kerogen samples from Qiongdongnan Basin and Liaohe Basin, a standard curve, regression curve Between free radical densities and burial depth of samples, has been established for paleogeothermal Gradient estimation. The paleogeothermal gradient of Carboniferous-Permian time of well MCl in Tarim Basin was estimated with this standard curve, which is reliable comparing with the result of being derived From vitrinite reflectance model.
