珠江口盆地新近系钙质超微化石研究综述

REVIEW OF THE NEOGENE CALCAREOUS NANNOFOSSIL RESEARCH OF THE PEARL RIVER MOUTH BASIN, SOUTH CHINA

根据珠江口盆地新近系钙质超微化石研究文献,综述了研究内容及发展过程。纵观二十多年来珠江口盆地新近系钙质超微化石的研究历史,大致可分成两个阶段(1)上世纪80年代初至90年代初,侧重于化石带的报道及主要化石属种的描述;(2)上世纪90年代中后期至今,主要为高分辨率钙质超微生物地层研究阶段。评述了以往研究中存在的问题,明确了今后研究的方向与任务。

Based on the researches of Neogene calcareous nannofossils from the Pearl River Mouth Basin, this paper briefly reviews the researching and developing process. The study of Neogene calcareous nannofossils from the Pearl River Mouth Basin in the last two decades could be subdivided into two stages： （1） from the beginning period of the 80＇s to early 90＇s of the last century, the studies focused on the calcareous nannofossil zones and the descriptions of main genera and species; （2） from the middle and late period of the 90＇s of the last century to the present, the researches concentrated on the high-resolution calcareous nannnofossil biostratigraphy. Both a review and a perspective of the study on Neogene calcareous nannofossils of this region are given.
