| 摘 要： | 用生物地层学方法对位于中太平洋同一座海山上的2块铁锰结壳样品进行了生物地层学详细研究,发现2块样品的生长层位对应,生物组合也相同.经鉴定,2块结壳的主要生长期都是晚古新世、中始新世至晚始新世、中中新世至上新世、上新世至更新世,2个主要的结壳生长间断分别在渐新世和早始新世.

| Abstract: | The detailed biostratigraphic research has been applied to two ferromanganese crusts which are sampled on a mid-Pacific seamount using the method of biostratigraphy.The results reveal that the growth layers of these two samples are homologous and their calcareous nannofossil complexes are the same,too. Based on the identification of calcareous nannofossil imprints and original fossil remains,the main growth periods of the two samples are Late Paleocene,Mid-Late Eocene,Mid Miocene to Pliocene and Pliocene to Pleistocene. On the other hand,the two main growth gaps are at Oligocene and Early Eocene. |
