湖北通山志留紀(jì)晚期地層的發(fā)現(xiàn)
[Abstract]:Based on a comprehensive study of the upper strata of the Silurian system in Tongshan, Hubei Province, many layers of linear plants and large fossils of insect tubules have been found in the strata of the original "Maoshan formation". Based on the research results of the upper Silurian strata in Guangyuan, Hunan, Zhangjiajie and Lixian in Sichuan, Xiushan in Chongqing, Shiqian and Injiang in Guizhou, it is proposed that the Tongshan area was originally classified as the formation of "Maoshan formation". Its geological age is late Silurian (Ludlow-Pridoli), known as the stream formation. In the southeast of Hubei Province (Daye-Chongyang area), the thickness of the Xixiu formation has thinned from south to north, and the sedimentary center of the formation is assumed to be in the northwest of Jiangxi Province.
