| 摘 要： | 根据近年笔乾研究，楚雄盆地中生代以后经历三期变形作用：早期（燕山期）主要发育于密者挤压逆冲带，显示横向置换特征，中期（喜马拉雅早期）是主变形期，西带显示由SW向NE逆冲，以叠瓦状闻和冲构造系统为其特征，晚期（喜马拉雅中晚期）发育于陡坡和深切割区，表现为重力滑动构造，这些构造期次的确定为研究该盆的发展，演化提供理论依据，亦为寻找油气资源提供靶区。

| Abstract: | The Chuxiong basin is a famous Mesozolic-Cenozoic basin in Yunnan Province.According to our recent studies,after Mesozoic,the Chuxiong basin experienced 3 periods of deformation.The rarliest one(Yanshanian)mainly developed in the Mizhe compressive thrust zone,showing lateral replacement characteristics.The middle(early Himalayan)is the main deformation,characterized by the imbricate thrust structure system,whose west zone shows thrusting from SW toward NE.And the latest one (middle-late Himalayan)is mainly developed in the steep slope and deep dissection area,showing a gravity sliding structure.The identification of them can provide a theoretical foundation for the study on development and evolution of this basin,and the target for finding oil-gas resources. |
