Late Mesozoic Comparative Research on the Geothermal Field of the Ordos Basin and Qinshui Basin

Ren Zhanli; Zhao Zhongyuan

Abstract

The Ordos basin and Qinshui basin, separated by the Iia lung uplift, are all large sdlimerto rybasins. It was detererned by many methods of vitrinite reflectance apatite fission track and fluid inclu-sign that paleogeothermal gradient and heat flow are 3.3-4.3℃/100 m and 81-95 m W/²in the Or-dos basin, 5.8℃/100 m and 106 m W/²in the Qinshui basin, and the Qinshui basin is higher is thesevalues than the Ordos basin. Those facts showed that there was a tectonic一hermal event in Late Meso一wic which occurred from Late Jurassic to Early Cretaceous. this tectoni cthermal event increased ther-mometamorphic degree of Palaeowic gas source rocks and ac elerated gas generation.
