本文初步研究了百色盆地那读组的沟鞭藻和疑源类,描述了11属25种,其中1新属、4新种、1新变种和2新组合种。根据藻类化石特征,自下而上划分了4个组合。较详细地讨论了其沉积环境(淡水湖相沉积),并认为它所代表的地质时代为早第三纪中晚期,即始新世晚期至渐新世,可能以渐新世为主。

The dinoflagellate cysts have been observed in the Yuyang formation of the Upper Cretaceous,the Qianjiang and the Xin—gouzui formations of the Lower Tertiary for the first time.The dinoflagellate assemblage in the Yuyang for- marion is comparable to that in the Upper Cretaceous Dalangshan formation, Sanshui basin,Guangdong province in general.The two dino-assemblages are probably contemporary products developed under similar paleoenvironments. Combined with other paleontological and sedimentological information,the dinoflagellate assemblages indicate that the sediments containing them may deposit in a brackish water body mainly controlled by both sea-flood and eva- poration under arid climate conditions.Different from marine assemblages in both general and detail,the nonmarine ones have been discussed in this paper.

本文报道了首次在江汉盆地上白垩统—下第三系的渔洋组、潜江组和新沟咀组中发现的沟鞭藻化石。渔洋组的沟鞭藻组合在总貌上十分相似于广东三水盆地晚白垩世大(土朗)山组的沟鞭藻组合,二者可能系同期、相似环境下的产物。沟鞭藻组合的特征分析结合其他古生物、地质等资料的证据说明,发育沟鞭藻的沉积是受海泛和干旱蒸发两个因素影响而形成的,半咸水环境下的产物,它们很可能是潜在的生油岩系。文章并总结了非海相沟鞭藻组合的特征,在总貌和细节上都不同于正常海相的组合。

This paper deals with Pleistocene dinoflagellate cysts from arenaceous dolomite in Hainan Island,China. Four genera and 10 species of dinoflagellates (including 1 new species)were described and illus-trated. The palaeoenvironment(warm temperate neritic) was also discussed on the basis of the environ-mental and ecologic distributions of dinoflagellate fossils.

该文所研究的样品采自海南省儋县排浦乡,为一套珊瑚岸礁海蚀坪潮间带的更新世砂质白云岩。作者对其中两块样品进行了分析研究,并获得沟鞭藻类囊孢4属10种,其中包括1新种2未定种。文中除了对这些属种进行了较为详细的描述以外,还讨论了它们所反映的古环境,认为含有这些化石的砂质白云岩是暖温带浅海环境下的产物。
