trenches developed during the Proterozoic, including the Yanliao rift trench, which started forming at 1.8Ga, and the Wumishan Formation, which was deposited during the middle Mesoproterozoic (Cui et al., 2000; Wang et al., 1995). The rift trough was formed last. Jixian County in Tianjin is located in the center of a strong depression of geological background with a total sedimentary thickness of 10,000m. The Wumishan Formation has a sedimentary thickness varying from 1,030m to 5,400m in the North China area. Jixian County lies in the center of strong depression of the Yanliao rift trench, strong depression of geological background,with sedimentary thickness reaching 3,300m, and belong to carbonates tidal flat deposit. Through macroscopic description of microbialites of the Wumishan Formation from the lower, middle, and upper typical profiles include1 M2, 2M6, 3 M8, and 4M11 as the second, sixth, eighth, and eleventh members of the formation, respectively, in Jixian County, Tianjin, China, JIN Tingfu, LI Youguo, LUO Ping and LI Pengwei, 2015.
