保山地区的石炭系,系指分布于崇山—杉阳—柯街—勐底—崇岗一线以西,怒江以东,北起泸水,南经保山、施甸直至镇康这一范围内的石炭纪地层。除中统缺失外,上、下统发育较好,岩相及古生物群独具特点。六十年代以来,建立了地层层序。1978年云南地层表将下石炭统从下而上分为鱼硐段、石花硐段及云瑞街段。本文主要根据1∶20万保山幅、风庆幅取得的地层古生物资料、提出本区石炭系分层系统古生物分带。
Carboniferous in Baoshan area refers to the area located in the range of Chongshan - Sunshine - Kejie - Mengdi - Chonggang, west of Nujiang, Lushui in the north, Baoshan and Shidian up to Zhenkang in the south Carboniferous strata. In addition to the absence of the Central Plains, the upper and lower epicontinental development is better, lithofacies and paleontology group unique. Since the 1960s, stratigraphic sequence has been established. In 1978, the stratigraphic map of Yunnan stratified the lower Carboniferous from the bottom up into the fish cave, the stone flower cave and the Yunrui Street. This paper mainly based on 1: 200000 Baoshan, Feng Qingfeng obtained paleontological data, proposed the stratigraphic system of the Carboniferous Paleozoic zoning.
