摘要
塔里木盆地南部早二叠世孢粉植物群可分为Striolatospora-Qipanapollis(SQ)组合和Potonieisporites-Vestigisporites(PV)组合,时代为早二叠世早、中期.对孢粉植物群特征的分析表明,在早二叠世早、中期,属于欧美植物群范畴,并非以往所认为的属于华夏植物群,也未发生所谓的四大植物区系的混生现象.对塔里木地块当时古地理位置的讨论结果亦支持这一结论.
The Early Permian sporopollen flora in southern Tarim basin could be divided into two assemblages, i.e. Striolatospora - Qipanapollis (SQ) assemblage (early period of Early Permian) and Potonieisporites - Vesligisporites (PV) assemblage (middle period of Early Permian) . The analysis of characteristics of sporopollen flora showed that the sporopollen flora in the early-middle period of Early Jurasssic belong to Euramerican flora rather than the previously recognized Cathaysian flora. The so-called 'mixed living' of Euramerican, Angaran, Cathaysian and Gondwanan flora is beyond the truth. This is also supported by the palaeogeographic location at that time in Tarim massif.
