摘　　要：在赣东北１／５万地质填图及上饶县清水乡缪源村下中侏罗统实测剖面基础上，提出林山组、罗坳组层序地层划分方案，分析了沉积体系的４种类型（冲积扇辫状河体系，辫状三角洲体系，湖泊三角洲与湖沼体系，曲流河体系），编制了赣东北地区早侏罗世古地理略图，总结了侏罗纪陆盆演化的５个发展阶段。Dealt with in this paper is the stratigraphic classification of the Linshan and Luoao Formations; four kinds of deposional systems are analyzed: the alluvial fan system, the braided delta system, the lacustrine delta system or the lake swarmp system and the meandering river system. The Early and Middle Jurassic palaeogeographic sketch in the northeast of Jiangxi is compiled, and five developement stages are summarized for the evolution of the Jurassic continental basin.
