摘要(Abstract):

本文论述了松辽盆地白垩系介形类化石分布的地层意义和介形类化石的盛衰与磁性地层的关系。认为介形类属是控制地层组的划分标志,介形类种是控制地层段的划分标志。讨论了介形类的盛衰与地层磁性变化的关系,并将介形类的分层与磁性柱进行了对比。
: The paper discusses the strata significance of the Cretaceous Ostracoda fossil distribution and the relationship between the flourish and decline of Ostracoda with Magnetostratigraphy. It is considered that Ostra coda's genus is the dividing criteria of controlling strata members. The relati-onshipbetween the flourish and decline of Ostracoda with the changing of Ma-gnetostratigraphy is discussed, meanwhile, Ostracoda stratigraphic division is compared with the magnet column.
