【摘要】 分析了四川南部晚二叠世聚煤盆地的前期构造环境背景。应用趋势面分析、厚度－相法结合其它地质因素的综合研究，将聚煤盆地的同沉积构造按地理位置、展布方向、规模大小与活动性质等分为４组１６个构造单元。并按隆起与坳陷、断裂阐述了具体特征及其对沉积环境体系、沉积相带展布和聚煤作用的控制。更多还原

【Abstract】 The present paper makes an approach to the coal-accumulating palaeostructural setting and synsedimentary structures in coal-accumulating basin in south Sichuan in Late Permian. By use of trend surface analysis and thickness-lithofacies analysis and according to geographical position, orientation,scale and activity, the synsedimentary structures are divided into 4 groups and 16 structural elements.Structural features of the structural elements and their sedimentary environment, facies and coal-accumulating control are expounded.更多还原
