摘要
罗马尼亚Dabuleni地区钻井岩芯的孢粉学研究揭露了一些丰富的微体浮游植物组合。根据孢粉学资料确定为始新世Bartonian-Priabonian期的地层产有丰富的沟鞭藻组合,包含Areosphaeridium diktyoplokus,Enneadocystamulticornuta,Batiacasphaera compta,Deflandrea phosphoritica,D.leptodermata,Hystrichokolpoma cinctum,Impagidiniummaculatum,I.sp., Palaeocystodinium golzowense,Rhombodinium rhomboideum,Samlandia chlamydophora,Spiniferitesramosus,Thalassiphora pelagica和Wilsonidium compactum等。文中描述Bartonian-Priabonian期的沟鞭藻一新属两新种:Chateauneufacysta moesica gen.et sp.nov.和Rhombodinium antonescui sp.nov.。
The palynological study of the cores from the borehole 20 at Dabuleni allowed identification of rich microphytoplanktonic assemblages. The deposits investigated palynologically were dated as Bartonian-Priabonian of Eocene, yielding abundant dinoflagellate assemblages, which involve Areosphaeridium diktyoplokus, Enneadocysta multicornuta, Batiacasphaera compta, Deflandrea phosphoritica, D. leptodermata, Hystrichokolpoma cinctum, Impagidinium sp., I. maculatum, Palaeocystodinium golzowense, Rhombodinium rhomboideum, Samlandia chlamydophora, Spiniferites ramosus, Thalassiphora pelagica, Wilsonidium compactum etc.Two new species and one genus of dinoflagellate cysts are described from this Bartonian-Priabonian interval. They are Chateauneufacysta moesica gen. et sp.nov. and Rhombodinium antonescui sp. nov.
