在对福建上杭上石炭统■类系统研究的基础上,根据类化石在地层中的分布和垂向变化规律,自下而上建立了2个■带:Profusulinella带和Fusulina-Fusulinella带。Profusulinella带细分为2个亚带:Profusulinellastaffellaeformis亚带和Profusulinella wangyui-Eofusulinatriangula亚带;Fusulina-Fusulinella带细分为3个亚带:Fusulinella helence-Pseudostaffellapaxadxa亚带,Beedeina meyiensis亚带及Fusulinaquasicylindrica亚带。通过与我国华南沉积区和欧美同期■类生物地层的对比,解决了本区上石炭统地层的时代归属,为福建以及我国石炭系的划分和对比提供重要的基础资料。
Based on the study of the Upper Carboniferous system in Shanghang, Fujian Province, two belt belts, Profusulinella belt and Fusulina-Fusulinella belt, were established from bottom to top according to the distribution and vertical variation of the fossil in the strata. The Profusulinella zone is subdivided into two sub-zones: the Profusulinellastaffellaeformis subline and the Profusulinella wangyui-Eofusulinatriangula subline; the Fusulina-Fusulinella subdivision into three sub-zones: Fusulinella helence-Pseudostaffella paxadxa, Beedeina meyiensis and Fusulinaquasicylindrica. By comparing with the similar biogenic strata in South China and the same period in Europe and America, this paper solves the age affiliation of the Upper Carboniferous strata in this area and provides important basic data for the division and comparison between Fujian and China’s Carboniferous.
