The Erlian Basin is one of the most important oil, gas, coal, and uranium-bearing basins in northern China, and basement granites of the Erlian Basin are gaining importance as uranium source and petroleum reservoir. However, the emplacement time and denudation history of the basement granites are poorly studied. Here, based on newly obtained zircon U-Pb geochronological data and zircon/apatite fission track evidence, the diagenetic age and uplift history of basement granites of the southern Jiergalangtu Sag, Erlian Basin are analyzed. The diage...
