摘要：Previous studies proposed thermal simulation experiment to investigate the annealing characteristics of fission tracks in igneous zircon samples. However, basic research about detrital zircon fission track was relatively weak. This study discussed the initial track length, annealing temperature and annealing model of zircon fission track by using the measured track lengths obtained from natural borehole samples in the sedimentary basins with different thermal background. The results show that the initial track length of zircon fission track is 12.97 mu m. The total annealing temperature (T-total) of zircon fission track derived from the evolutionary curve of the mean track lengths is approximately 400 degrees C. The temperature ranges of 120-230 degrees C corresponds to the partial annealing zone (PAZ), and is lower than the range obtained through thermal annealing experiments. The annealing model is modified based on the measured track lengths. In addition, a functional formula about the mean track length, annealing temperature, and geological time is proposed, and the fitted values of track lengths consist with the measured track lengths in this study. By properly understanding the initial track length and annealing behavior of zircon fission track can provide a significant guidance for the study of hydrocarbon accumulation in sedimentary basins.
