Abstract

Abstract:

Spores of 36 genera, 56 species and some indeterminate species are recognized from 8 layers of Wutong Formation at Jianchuan Section, Xinhang County, Guangde City, Anhui Province. A spore assemblage can be established, that is Apiculiretusispora hunanensis-Cymbosporites chinensis (HC) Assemblage. By comparing the main components of HC Assemblage with spore assemblages in South China, Tibet of China and Western Europe, HC Assemblage is assigned to the late Famennian of the Late Devonian and corresponds to the strata except the uppermost part of the Leigutai Member of the Wutong Formation. The overall characteristics of HC Assemblage are close to contemporaneous assemblages of South China but different from those of Tibet of China and Western Europe.

Key words: spore assemblages, Famennian, Wutong Formation, Leigutai Member, Anhui

摘要：

在安徽省广德市新杭镇箭穿剖面五通组的8个层位中识别出孢子36属56种及部分未定种, 并建立1个孢子组合, 即Apiculiretusispora hunanensis-Cymbosporites chinensis (HC)组合。与中国华南、西藏以及西欧地区孢子组合的对比结果表明, HC组合的形成时代属于晚泥盆世法门期晚期, 层位相当于五通组擂鼓台段除顶部之外的地层。HC组合的整体面貌与华南其他剖面的同期组合接近, 但与中国西藏及西欧地区有明显的差别。
