摘要
本文描述了海拉尔盆地早白垩世沟鞭藻新属种,共2属8种,其中1新属、3新亚属,8新种。建立4个沟鞭藻组合带,探讨了含藻类化石层位的沉积环境,并据藻类化石的兴衰更替,推测了盆地最有利的生油环境。
<ABSTRACT> This paper desfribes the new genera and species of early Cretaceous
Dinoflagellates of Hailaer Basin .They cnsist of 2 genera with 8 species including
1 new genus, 3 new subsenera and 8 new species.Four Dinoflagellate assemblage zones are established, It discusses the sedimentation environment of the horizones containing algal fossiles, and according to the rise, decline and replacement of algal fossiles infers the most favorable environment for oil generating in this basin.
