微山湖西侧地区,北至鱼台、单县一带,南至徐州,西南同皖北、豫东为邻。区内二叠系几乎均被新生界所覆盖,仅丰县华山等地稍有出露。本文将在该区勘探中所揭露的实际材料,从其岩性、岩相、物性及古生物特征研究后,提出一些新的认识及识别标志,同时在同国内同期地层对比后,对该区的地层作了新的厘定及划分。文内植物化石除少量由笔者鉴定外,由李星学、张善桢、莫壮观等鉴定或审核,腕足化石由许汉奎鉴定。
Weishan Lake west of the area, north to Yutai, Shanxian area, south of Xuzhou, southwest with the Northern, Eastern Henan Province. The Permians in the area are almost all covered by the Cenozoic, only Huaxiang Fengxian and other places slightly exposed. Based on the study of lithology, lithofacies, physical properties and palaeontology, this paper presents some new recognitions and identification signs of the actual materials exposed in the exploration of this area. After comparing with the same period of the same period in China, Stratigraphy made a new determination and division. In addition to a small amount of plant fossils identified by the author, by the Li Xingxue, Zhang Shanzhen, Mo Zhuangguang appraisal or review, the fossil bracers identified by Xu Hankyu.
