| 摘 要： | 据30属57种(包含9新种)小孢子的垂直分布特征,将江西全南小慕泥盆一石炭系的小孢子划分为3个组合(自下而上):1)Acanthotriletes denticulatus-Apiculireiusispora raris(DR)组合,2) Leiotriletes macrothlis-Grandispora xiamuensis(MX)组合,uispinosa(TT)组合,3)Apiculiretusisporatera-Lycospora cf. thuispinosa(TT)组合.这3个组合分别产于三门滩组、翻下组与荒塘组-刘家塘组.据孢子资料的分析与植物、腕足类、鱼类等化石的佐证,三门滩组与翻下组的时代均属晚泥盆世晚期(Famennian),荒塘组与刘家塘组属早石炭世早期(Tournaisian).本区泥盆系与石炭系的界线置于翻下组与荒塘组之间较适合.

| Abstract: | Three Devonian-Carboniferous miospore assemblages have been recovered from the Xiaomu Section, approximately 10km northwest of Quannan, Jiangxi. This section mainly includes the Liujiatang-Huangtang, Fanxia and Sanmentan Formations, which are briefly described in ascending order as follows (Text-fig. 1):
