摘要
银厂坡一七〇厂地区的上石炭统发育,含(虫筳)丰富。自下而上可划分为Protulinella-Pseudostaffella,Triticites和Pseudoschwagerina-Eoparafusulina三个(虫筳)类化石带。著名的Fusulina-Fusulinella带在此区缺失。上石炭统可划分为上部的马平组和下部的银厂坡组,其中银厂坡组为作者建立的新组。
Fusulinaceans are abundant in the Upper Corboniferous strata within theYinchangpo-Qilingchang district. The following three Fusulinacean zonescan be recognized: the zone of profusulinella-pseudostaffella, the zone ofTriticites, the zone of Pseudoschwagerina-Eoparafusulina. The famouszone of Fusulina-Fusulinella is gapped. The whole Upper Carboniferousstrata can be divided into two formations: Upper Maping Formation andLower Yinchangpo Formation. The latter is a new formation first named hythe authors of this paper.
