(U-Th)/He thermochronometry constraints on the Mesozoic-Cenozoic tectono-thermal evolution of Kuqa basin: A case study of well TZ2

Based on the tested apatite and zircon He ages data from drilling well samples, the He closure temperature of borehole apatites from Kuqa basin is determined (about 89 degrees C) by analyzing the relationship between apatite ages of (U-Th)/He and depth/temperature in profile. Mesozoic-Cenozoic thermal history of the well TZ2 will has been modeled by using the He ages and vitrinite reflectance (R-o) data. The modeling result shows that the forming time of Tuziluoke anticline started at 5 Ma, and it uplifted and eroded about 670 m in Cenozoic period with the average erosion rate of 0. 133 mm/a. According to structural evolution analysis of Tuziluoke anticline, the time of gas-migrating fault activity and trap formation was determined, which demonstrated the time o...

Zircon entrained within kimberlite deposits should have distinctive U–Th–Pb–He signatures compared to those found in the host terrane. To investigate the application of zircon double dating to kimberlite diamond exploration, we analysed zircon from the Sacramore kimberlite pipe located in the Merlin field in the Northern Territory of Australia. We also conducted a double dating study of detrital zircon from a regional sample of the Bukalara Sandstone, the principal host rock for the Merlin field. Repeated analysis of Fish Canyon zircon verified that the ion microprobe sputtering process used for U/Pb dating does not disturb the He content of the sample. The zircon U/Pb age for the Sacramore pipe (n = 14) ranged from 1541–2433 Ma, consistent with the Mesoproterozoic formation of the North Australian...
