Neoproterozoic Tectonic Attributes and Their Petroleum Geological Significance in Sichuan Basin
,
According to geochemical information analysis of Neoproterozoic igneous rocks in the periphery and interior of Sichuan basin, there are two completely different understandings of extension and extrusion. The geophysical data show that the deep rifting of the basin is widespread, and there are obvious uplift and denudation in the central and western parts of the basin until the deposition period of Doushantuo Formation. The tectonic transformation process between the two is unclear. To solve these problems, in this paper it explores the Neoproterozoic tectonic evolution and favorable oil and gas areas of the Sichuan basin through the interpretation of seismic reflection profiles and the analysis of petrogeochemistry, drilling data and outcrop sedimentary sequences. The results in this study show that the oceanic subduction was the cause of the rift-uplift denudation transformation in the western and central Sichuan during the period from the breakup of the Rodinia supercontinent to the convergence of the Gondwana supercontinent, while the eastern Sichuan area was always in tectonic subsidence in the middle and late Neoproterozoic (820-551 Ma).There may only be organic rocks of Wuye Formation at the same time in the Neoproterozoic of western Sichuan and central Sichuan, and clastic reservoirs are developed between the uplift area of central Sichuan and the subsidence area of eastern Sichuan.
