肥城煤田石炭纪类动物群及其地层划分

肥城煤田石灰纪含煤岩系的石灰岩中含较丰富的类化石，经研究计有１４属４２种，主要产于本溪组的五灰及太原组的一、二、四灰，根据类演化发育阶段和在地层上的垂直分布规律，自下而上建立了三个化石组合带，即：１．Ｆｕｓｕｌｉｎｅｌｌａ－Ｆｕｓｕｌｉｎａ组合带；２．Ｐｓｅｕｄｏｓｃｈｗａｇｅｒｉｎａ组合带；３．Ｔｒｉｔｉｃｉｔｅｓｐａｒａｍｏｎｔｉｐａｒｕｓ组合带。以上三个组合带经与华北、华南相关类动物群的对比，含三个化石组合带的地层分别代表了中石炭世中晚期和晚石炭世的沉积。此外，通过类及其他动植物群特征和空间分布的研究，对本区长期以来悬而未决的中、上石炭统和石炭、二迭纪界线进行了探讨。

FUSULINID FAUNA AND ITS STRATIGRAPHICAL DIVISION OF CARBONIFEROUS IN FEICHENG COALFIELD,SHANDONG PROVINCE

The fusulinid fossils are fairly abundant in the limestones of carboniferous coalbearing System in Feicbeng Colfield and the authors discovered a total of 14 gerera.42Species.According to the evolutionary stage and the law of vertical distribution of fusulinidfaunas,three Assemblage zones may be recognized from the middle-upper carboniferous of which one Assemblage zone belongs to the penchi Formation and two Assemblage zones aredesignated to the Taiyuan Formation.They are shown in descending order as follows:Taiyuam Formation:(3)Triticites paramantiparus Assemblage zone;(2)Pseudoschwagerina Assemblage zone;Penchi Formation:(1)Fusulinella-Fusulima Assemblage zone.In this locality,three Assmblage zoneswere compared with similar Fusulinid Assemblage zones of middle-upper carboniferous inNorth and South China.The geological age of fusulinid-bearing strata respectively belongto the middle-late period of middle carboniferous and late carboniferous.In addition,on thebasis of detailed study on properties and spatial spreads of the fusulinid and the animal-plant fossils,we have made a further revisal to the boundaries of middle-upper carbonifer-ous and carboniferous-permain stratigraphies in Feicheng Coalfield.
