| 摘 要： | 新近系各阶全球层型剖面和点位( GSSP)的选定工作近年来取得了许多实质性的进展,至今上新统3个阶的GSSP已全部获得批准,中新统有3个阶获批准、2个阶有望在2 0 0 4年获得通过、1个阶的指示事件尚未确定,有待进一步的工作。除介绍新近系各个阶最新的GSSP内容外,还就中国陆相新近系建阶工作的进展和研究重点作了简要的回顾与展望,认为上新统麻则沟阶、高庄阶和中新统谢家阶有望在命名剖面定义底界的界线层型和点位,中新统保德阶、通古尔阶和山旺阶的底界有待在甘肃临夏盆地、兰州盆地和秦安地区寻找。中国陆相新近系建阶工作的开展与完成,会给中国地层学研究工作带来积极而又深远的影响。

| Abstract: | Some fundamental progresses have been made in selecting the Neogene Global Stratotype Sections and Points (GSSPs) by the International Commission on Stratigraphy in recent years. There have been so far three ratified stages in Pliocene, three ratified, two anticipated stages for GSSPs, and one with guide event undecided in Miocene. This paper gives an updated overview of these Neogene GSSPs, toge- ther with a general review of the efforts in establishing the continental Neogene Stages in China. According to the Regional Chronostratigraphic Chart of China, there are Mazegouan and Gaozhuangian Stages in the Pliocene, Baodean, Tunggurian, Shanwangian and Xiejian Stages in the Miocene, which are correlated with Piacenzian, Zanclean, Messinian and Tortonian, Serravallian and Langhian, Burdigalian, and Aquitanian Stages respectively. Some efforts were made in determining their stratotype sections and points in the past three years. Further studies are still anticipated in several potential basins for the stratotype sections and points. This work will turn out to be highly worthy for promoting the precision in the stratigraphic correlation of China. |
