摘要在南极洲南维多利亚陆群（上灯塔超群）中发现了33个植物微化石组合，其中许多保存较差。孢粉演替中有三个广泛的组合带，非正式地称为Parasaccites带（最古老的），Protohaploxypinus带和Alisporites带。带被明显缺乏植物微化石的地层隔开。在达尔文提利岩、俄亥俄山脉和威斯康辛山脉的类似岩石中，以及尼尔森高原的提利岩上覆的页岩中，都出现了副长岩带组合。在澳大利亚晚石炭世和二叠纪孢粉带方案中，副accites带与澳大利亚二叠纪-石炭世冰川沉积的上2期相对应。含gloopteris - Weller煤系中上部的Protohaploxypinus带类似于澳大利亚早二叠世（Artinskian）时代的第4阶段。Assembla……
Abstract Thirty-three plant microfossil assemblages, many of which are poorly preserved, have been recovered from the Victoria Group (upper Beacon Supergroup) of south Victoria Land, Antarctica. Three broad assemblage zones, informally designated the Parasaccites zone (oldest), the Protohaploxypinus zone, and the Alisporites zone, are recognisedin the palynological succession. The zones are separated by strata apparently lacking plant microfossils. Parasaccites zone assemblages occur in the Darwin Tillite, in equivalent rocks in the0 Ohio and Wisconsin Ranges, and in shales overlying tillite in the Nilsen Plateau. In terms of the Australian Late Carboniferous and Permian palynological zonal scheme the Parasaccites zone is correlated with upper Stage 2 from Permo-Carboniferous glacial and f1uvioglacial deposits in Australia. The Protohaploxypinus zone from the middle and upper parts of the Glossopteris-bearing Weller Coal Measures resembles the Australian Stage 4 of Early Permian (Artinskian) age. Assembla...
