摘要
本文描述了东海陆架盆地西南部始新世有孔虫55种,分属27属19科,其中浮游有孔虫22种,划分为四个组合,底栖有孔虫33种,划分为五个组合;瓯江组、温州组及平湖组时代分别定为早、中、晚始新世,但从有孔虫面貌看,温州组下部(包括浮游有孔虫组合2及3和底栖有孔虫组合2)似有属于早始新世的可能。
Described and illustrated in this paper are 55 species of Eocene foraminiferabelonging to 27 genera collected in the debris core samples from the southwesternEast China Sea Shelf. The fossils yielded in adjacent strata are possibly mixed.It is difficult to divide exactly the foraminifera into zones; they can only bedivided into four planktonic foraminiferal assemblages and five benthonic forami-niferal assemblages (see Table below).
