Abstract:
The sedimentary facies of Upper Permian Wujiaping Formation at Gediba section in the northwestern Sichuan is carbonate platform, its microfacies type and evolution can be used to reveal the shallow water sedimentary characteristics and the distribution of favorable facies of Wujiaping Formation in the northwestern Sichuan. The strata of Wujiaping Formation is well outcropped with a thickness of 69.55 m and divided into three lithologic members from bottom to top. Various biological types, such as benthos and plankton, are distributed, and some reef-building biologies are in-situ growth state, which show that they grow in shallow water environment with certain reef-building capacity. The microfacies types of limestones include micritic limestone, foraminiferal wackestone, intraclastic wackestone, bioclastic wackestone, bioclastic packstone, intraclastic-bioclastic packstone, intraclastic packstone and micritic biological limestone, and the thicknesses of bioclastic packstone and bioclastic wackestone are the largest. There are several sedimentary sequences of packstone and wackestone in vertical, and interclastic is filled with calcite-mud, and δ13C value are medium-light with low amplitude oscillation. The above characteristics indicate that there is a relatively weak turbulent shallow marine environment with frequent sealevel fluctuations during Wujiaping depositional period in the northwestern Sichuan.
