| Abstract: | This paper focuses on the study of basin-and-range relations about Kongquehe slope and Kuruketage uplift. Thermochronology constraints were made to the key tectonic events in the Kuruketage tectonic evolution history, using the methods of detrital zircon and apatite fission track, sampled from outcrop area and well cores. The time of the maximum palaeotemperature from zircon samples was determined during late-Caledonian to early-Hercynian cycle, and from then on, the samples experienced the procedure of tectonic uplifts and temperature drop times. Two thermochronology ages of zircon fission track were recorded, which reflect two tectonic events happened in 371~392 Ma and 328~305.7 Ma. Three later tectonic uplifting events were recorded by apatite fission track, whose thermochronology ages are 134.5~164 Ma, 73~100 Ma and 35.4 Ma respectively, after the palaeotemperature of samples was decreased out of the partial annealing zone's base level. The Hercynian ages from the zircon samples indicate the tectonic transformation from subsidence to uplift in the Kongquehe slope, which is significant to oil-gas reservoir formations, and the late-Cretaceous tectonic event showed by the apatite samples reflects intense uplifting of the Kuruketage Mount. |
