摘　　要：本文综合介绍了昆阳群沉积盆地构造性质和构造样式,提出了今后开展研究的趋势内容和方法;对昆阳群层序构建方面,除高精度测年、生物演化研究外,应重视沉积建造序列分析,从沉积盆地的构造活动性、迁移性方面去探讨沉积作用时间演化与空间变化的关系;在概述昆阳群火山活动、构造变形作用、变质作用时空演化特征及相互联系基础上,指出因民期火山作用对成矿的贡献应予以肯定,且是今后值得进一步研究的内容。In this paper,we have introduced comprehensively the structural nature and pattern of Kunyang Group sediment basin,put forward the future study trend project and method.To the set up of stratigraphic sequence of Kunyang Group,we must pay attention to the analysis of sediment formation series besides the high precision dating and biological evolution study,to probe into the relationship between time and space evolution of sedimentation in the structural activity and migration.Basing upon the review of Kunyang Group volcanism,structural deformation,time-space evolution and connexion each other of metamorphism,we put forward that we must pay attention to the contribution of Yinmin volcanism to the metallogenesis,which must be the future study project.
