福建宁化上石炭统达拉阶的类

FUSULINIDS OF THE UPPER CARBONIFEROUS DALAN STAGE FROM NINGHUA,FUJIAN PROVINCE

通过对福建宁化县泉下镇石灰窑下村上石炭统达拉阶类的系统研究,共描述类10属35种,包括3个未定种。根据类化石在地层中的分布和垂向变化规律,自上而下建立两个带、三个亚带:II.Fusulina Fusu linella带,3)Fusulinaquasicylindrica亚带,2)Beedeinamayiensis亚带和1)Fusulinellahelenae Pseudostaffella paradoxa亚带,I.Pseudoendothyraninghuaensis带。为该区以及我国石炭系地层的划分和对比提供重要的素材。

By a systematic study of the fusulinids in the Upper Carboniferous Dalan Stage from the Quanxia village of Ninghua, Fujian Province, 10 genera and 35 species of fusulinids have been found, including 3 species indeterminate. According to the geographical distribution and vertical variation of fusulinids in the strata, 2 fusulinid zones are recognized as follows （in descending order） ： Ⅱ. Fusulina-Fusulinella Zone, including 3 subzones, 3）Fusulina quasicylindrica Subzone, 2） Beedeina mayiensis Subzone and 1 ） Fusulinella helenae-Pseudostaffella paradoxa Subzone, Ⅰ. Pseudoendoth yra ninghuaensis Zone.
