贵州六枝—盘县地区早二叠世隆林期类组合与沉积环境

六枝—盘县地区的早二叠世隆林期地层,相区分异明显、类化石数量巨大。各相区类化石群落特征差异较大:半局限台地相为Staffella-Nankinella-Pisolina;台地边缘生物滩(礁)相为Parafusulina-Pseudofusulina;斜坡-盆地相为Pseudofusulina,进一步划分为近岸碳酸盐上缓坡环境的Staffella-Parafusulina-Wentzellophyllum群落、远岸碳酸盐上缓坡环境的Pamirina-Schwagerina-Pseudofusulina群落、碳酸盐下缓坡环境的Pseudofusulina-Robustoschwagerina-Kepingophyllum群落和盆地环境的Pseudofusulina-Schwagerina-Verbeekiella群落。

The Longlinian(Early Permian) fusulinid communities and sedimentary environments in the Liuzhi-Panxian region,Guizhou

The fusulinid communities are quite variable in the Longlinian(Early Permian) strata in distinct(sedimentary) environments in the Liuzhi-Panxian region,Guizhou: Staffella-Nankinella-Pisolina community in the semi-restricted platform facies;Parafusulina-Pseudofusulina community in the platform-margin organic shoal(reefs) facies,and Pseudofusulina community in the slope-basin facies.Four communities may further be(recognized) for the last one outlined above,including: Staffella-Parafusulina-Wentzellophyllum community in the nearshore upper carbonate ramp environment;Pamirina-Schwagerina-Pseudofusulina community in the offshore upper carbonate ramp environment;Pseudofusulina-Robustoschwagerina-Kepingophyllum community in the lower carbonate ramp environment,and Pseudofusulina-Schwagerina-Verbeekiella community in the basin environment.
