摘　　要：江西地区以陆相沉积为主的古近系岩石是在继承白垩系基础上发育起来的,经过长期风化、剥蚀,接受了巨厚的沉积。从目前古近系沉积厚度来看武宁群(包括修水、安义一奉新盆地)为775~179m;清江盆地为779.1~1654.6m;大余池江盆地为1513.8m。由于同一盆地的岩性、岩相变化急剧,它们时代相同,而岩相各异,很难进行层位对比。因此本文对江西古近系岩相、古地理、古气候及古植被情况及矿产资源情况进行了归纳与总结。The Paleogene predominated by continental sediments in Jiangxi Province was developed on the basis of the Cretaceous.The Paleogene is 775-179 m thick in the Anyi-Fengxin basin and Xiushui,and 779.1-1654.6 m thick in the Qingjiang basin and 1513.8 m thick in the Dayu basin.Gigantic changes in thickness,lithology and sedimentary facies of the Paleogene in the same basin make stratigraphic correlation difficult.This paper makes an approach to sedimentary facies,paleogeography,paleoclimate,palaeovegetation and mineral resources of the Paleogene in Jiangxi.
