| 摘 要： | 本文根据重庆中梁山长兴组中腕足动物的分布规律,建立了下部的Spinomarginifera chengyoayenensis-Qinglongia acutangulum组合和上部的Perigeyerella costellata-Enteletina transversa组合,阐述了各组合的面貌和特征。还对中梁山长兴组腕足动物的时代特征进行了讨论,并与邻区同期的腕足动物群进行了比较。为中梁山、华山各矿井寻找断失翼煤层提供了古生物依据。

| Abstract: | According to the distribution of Brachiopoda in the Changxing Formation in ZhongLiangShan, Chongqing, the present paper has established the Spinomarginifera chengyoayenensis - Qinglongia acutangulum assemblage in the lower and the Perigeyerella costellata - Enteletina Transversa assemblage in the upper, and has discussed their features. It has also dealt with the age of Brachiopoda, and correlated the Brachiopoda with those in the neighborhood in the same age. All of these data provide palaeontologic criteria for the searching for the faulted coal seam hiatus in the mine fields in the Zhongliangshan and Huayingshan coalfiels. |
