浙江早古生代孢粉型化石的研究

EARLY PALEOZOIC PALYNOMORPHS OF ZHEJIANG PROVINCE,CHINA

在浙江西北部早寒武世荷塘组、晚寒武世华严寺组、早奥陶世宁国组、晚奥陶世长坞组和文昌组、早志留世霞乡组、河沥溪组和康山组、中志留世唐家坞组中发现孢粉型化石,孢粉型化石包括疑源类,隐花(陆生)植物孢子类型等,计66属、112种、31未定种。同时讨论了这9个层位孢粉型化石的组合特征、地质时代及其沉积环境。

The paper reports Early Paleozoic palynomorphs from the Early Cambrian Hetang Formation, the Late Cambrian Huayansi Formation, the Early Ordovician Ningguo Formation, the Late Ordovician Changwu Formation and Wenchang Formation, the Early Silurian Xiaxiang Formation, Helixi Formation and Kangshan Formatiom, and the Middle Silurian Tangjiawu Formation in northwestern Zhejiang Province. These fossils include acritarchs and cryptospores assigned to 66 genera, 112 species and 31 undetermined species. The geologic age and depositional environments of these palynomorph assemblages are discussed.
