呈北西-南东向展布的哀牢山构造变质带,以其独特的线形延伸、复杂而多期的变质迭加以及变质带东西两侧地质演化的明显差异,早为云南乃至国内外的地质工作者所瞩目,长期以来是讨论云南地质构造的核心课题(范承钧,1986)。这一带地区以往地质工作以1∶100万和1∶20万区调成果为主,近年来随着1∶5万区域地质调查和科研工作的深入开展,对哀牢山构造变质
The Ailao Mountain tectonic metamorphic belt that is distributed from northwest to south is characterized by its unique linear extension, complex and multi-period metamorphic superimposition and the obvious difference of geological evolution on the east and west sides of the metamorphic zone. It was earlier in Yunnan and even at home and abroad Geologists have drawn attention and have long been discussing the core issue of Yunnan’s geological structure (Fan Chengjun, 1986). In the past, the geological work in this area was dominated by 1: 1 million and 1: 200,000 regional seismograms. In recent years, with the 1: 50000 regional geological survey and scientific research carried out in depth, the structure of Ailaoshan
