英文摘要: Abstract(#br)This study uses a new application of the apatite and zircon (U–Th)/He thermochronometry technique to investigate the thermal history and tectonic uplift of sedimentary basins. Based on measured apatite and zircon (U–Th)/He ages, apatite fission track data and equivalent vitrinite reflectance measurements of borehole core samples, the thermal history of the Bachu Uplift of the Tarim Basin was modeled. Our analysis indicates a complicated thermal history in the Bachu Uplift region during the Paleozoic. The thermal gradient initially increased from 28–30°C/km in the Cambrian period to 30–33°C/km in the Ordovician period and increased up to 33–34°C/km in the Silurian period. The thermal gradient began to decrease during the...
