摘要
藏南特提斯域内伸展运动和伸展作用非常普遍 ,根据构造变形分析和伸展不整合、沉积岩相、古地理再造及岩相对比方法 ,对藏南海西期以来的伸展构造进行了较为系统的厘定 ,确定了海西期、印支期、早燕山期的主动伸展运动和晚燕山期和喜山期的被动伸展作用 。
Extensional movement and extending action are well developed in the Tibetan Tethys domain.Based on the analysis of tectonic deformation,extensional unconformity,sedimentary facies and paleogeographical rebuilding of southern Tibet,it is recognized that the extensional movement consists of active extension of Hercynian,Indo Chinese and Early Yanshan epochs,and passive extension of the Himalayan epoch.Some of the characters of extensional movement and extending action are discussed in this paper.
