摘　　要：一般认为兰坪-思茅盆地“中轴构造带”两侧存在明显的演化差异。在云南宁洱县-正兴地区1∶50000勐烈、上把边、德化、普洱县、震东5幅区域地质调查工作中,对调查区内兰坪-思茅盆地演化历史、地层分布、沉积环境等作了系统研究。以中轴构造带为界,兰坪-思茅盆地在宁洱至正兴地区,盆地东西侧分别记录了不同的沉积演化历史,地层分布与岩性组合差异十分明显,因此,在宁洱至正兴一带,中轴构造带对兰坪-思茅盆地的演化控制作用明显。It is generally believed that there are significant evolutionary differences on either side of the“central structural zone”in theLanping-Simao Basin.Systematic studies were conducted on the evolution history,stratigraphic distribution,and sedimentary environment of the Lanping-Simao Basin duringa 1:50,000 geological survey of 5 areas,including Menglie,Shangbabian,Dehua,Pu'er County,and Zhendong,in Zhengxing area,Ning'er County,Yunnan.Divided by the central axis tectonic zone,the Lanping-Simao Basin is located in the Ning'er to Zhixing area.Different sedimentary evolution histories have been recorded on the eastern and western sides of the basin,with significant differences in stratigraphic distribution and lithological combinations.Therefore,the central axis tectonic belt has a significant controlling effect on the evolution of the Lanping-Simao Basin.
