摘要
赣西北修水—永修地区的盖层系统中具备多层次、多级别滑脱构造，本文重点阐述了该滑脱构造的基本特征，并对其形成时代及形成机制进行了探讨，认为该区早期属于挤压体制，晚期则属于伸展状态下的重力滑脱体制，并提出印支—燕山期板块碰撞、地形差异及九岭山体不对称挤压是诱发滑脱构造形成的主要因素。
Multi－horizon and multi－order decollement structures are recognizable in the covering strata system in Xiushui－Yongxiu area of Northwest Jiangxi． This paper lays emphasis on the basic features of these decollement structures, and discusses their ages and mechanism of formation, suggesting that compression prevailed in the early stage, while extension and gravity sliding took place in late stage, and that the leading factors for the formation of these decollement structures include: plate collision in Indosinian－Yanshanian times, difference in landform, and asymmetrical compression of the Jiuling Mountains．
