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.
