Zircon He diffusion kinetics models and its implications on the thermal history reconstruction of the ancient strata in the craton basins, China
摘要：Although the ancient strata of the sedimentary basins in China have become the important oil and gas exploration target, their thermal history evolution is still ambiguous due to the lack of effective paleo-thermal indicator. Based on a systematic review of zircon He diffusion kinetics models and their differences, this paper investigates the applicability of zircon (U-Th)/He dating in the thermal history reconstruction of ancient strata for the craton basins in China. The zircon He diffusion kinetic models include the simple model, the zircon radiation-damage accumulation and annealing model, and the fanning linear model. Thermal simulation indicated that the zircon radiation-damage accumulation and annealing model and the fanning linear model have a strong consistency when constraining the low-temperature thermal history but have a significant difference when constraining the high-temperature thermal history (>200 degrees C). The single-grain zircon (U-Th)/He ages of Precambrian samples from the Tarim Basin, Sichuan Basin and North China Craton Basin are all younger than the stratigraphic ages and negatively correlated with the effective uranium concentration, implying that radiation damage probably caused the dispersion of zircon (U-Th)/He ages. The forward and inverse simulation reveals the thermal history of the Precambrian samples from these three basins since the deposition and the experienced highest temperature of 160 similar to 185 degrees C, which has important significance for the maturation evolution and resource evaluation of the deep and ancient strata.
