摘要
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. 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.
