贺兰山呼鲁斯太煤田位于宁夏东北部,处于华北陆台、祁连山地槽的毗连处。贺兰山石炭纪地层厚度大,含灰岩多。研究该区石炭纪地层对煤田地质勘探及邻区地层划分对比都有一定的意义。现仅选含灰岩层数最多,厚度较大,动植物化石较丰富,地层出露良好的呼鲁斯太地区作一报道。本文所附化石资料,除部分由笔者鉴定外,皆承中国科学院南京地质古生物研究所鉴定。
Helanshan Huluosi Coalfield is located in northeastern Ningxia, in the North China Lutai, Qilian Mountains adjacent to the trough. Helan Mountain Carboniferous strata thickness, with limestone and more. Studying the Carboniferous strata in this area has certain significance for the geological exploration of coalfields and the stratigraphic division of the adjacent areas. Now only choose to contain the largest number of limestone layers, thicker, flora and fauna fossil rich, stratum well exposed Huludao too make a report. This article attached to the fossil data, with the exception of some of the identification by the author, Jie Cheng Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences identified.
