摘要
鄂尔多斯盆地火山活动、地温场、热流场、古地温、构造演化等方面的综合研究表明,该盆地的构造热演化为流体流体、流体岩石之间的相互作用提供了基础,为有机矿产和砂岩型铀矿的形成创造了条件,尤其是中晚侏罗世白垩纪的构造热事件,在铀源物质的提供、铀的运移,铀的富集和沉淀成矿等方面起着重要的作用。
The comprehensive study of the volcanic activities, the geothermal field, the thermal flow field, the paleogeo-thermal activity and the tectonic evolution of the Ordos basin indicates that the tectonic-thermal evolution of the Ordos basin has offered the basis for the fluid-fluid and fluid-rock mutual reactions, and has created favourable conditions for the formation of organic mineral resources and sandstone-type uranium deposits. Especially, the tectonic-thermal event during Middle-Late Jurassic to Cretaceous played an important role in providing uranium source material, and assisting the migration, the concentration and precipitation of uranium and uranium ore-formation.
