摘　　要：兰坪盆地于古特提斯末期进入裂谷盆地阶段。燕山末期—喜马拉雅早期,西带发育沟通地幔的铁各断裂组及由西向东逆冲推覆构造,形成区域上第一期导矿、容矿构造;喜马拉雅中期形成斜冲断裂,导致发育由东向西推覆构造,形成盆地东带导矿容矿构造,完成了盆地内最重要的成矿期次。构造演化控制盆地的沉积作用、火成活动。与成矿有密切关系。The beginning of rift stage of Lanping basin is from the last period of Tethyan.From last Yanshanian to early Himalayan,the development of Tiege fault set in connexion with mantle and the eastward thrust nappe results in the formation of regional ore-channel and ore-bearing structure and fulfills the most important metallogenesis in the basin.The structural evolution has controlled the sedimentation and igneous activity in the basin,which is in close relation with the metallogenesis.
