| 英文摘要 | The burial history and geothermal history reconstruction of the sedimentary basins is an important basis for understanding the genesis and hydrocarbon formation conditions of the basin. So far, there are very few achievements in the study of the burial and geothermal history of the Dongsha Uplift in the Pearl River Mouth Basin. In our research, geothermal history inversions based on apatite and zircon (U-Th)/He data give out more reasonable constraints, by which we perform another round of simulation on the same set of vitrinite reflectance Ro so as to obtain a delicate burial and geothermal history since the Mesozoic. Further thermal inversion reveals an intensive uplift and exhumation from early Eocene to early Oligocene with a denudation amount to about 2 km. The bottom heat flow for the LF35-1-1 well area also experienced a peak value of 100 mW . m(-2) in early Eocene (similar to 55 Ma) and decrease to 64. 3 mW . m(-2) at present. The good consistence between the maximum palaeo-geotemperture and the beginning of denudation confirms the effect of uplift on the decrease of geo-temperature, but not enough to rule out factors such as basal heat flow decline. This is the first try to apply (U-Th)/He technology on the thermal history study of the deep water area on the northern margin of the South China Sea. Moreover, the co-simulation method on the basis of multiple geothermometers, whose results are more agreement with the existing achievements in terms of structure and deposition settings, has got well efficiency in the thermal history study. |
