摘要
滇西兰坪盆地的形成和发展经历了漫长且复杂的历史过程 ,由洋盆→洋陆转换→陆内盆地→盆山转换等过程。根据盆地充填和造山带特征 ,讨论兰坪盆地的演化历史及盆山对应关系。通过对兰坪盆地地质资料综合分析 ,可将兰坪盆地及周缘造山带的演化历史分为三个阶段 :兰坪地块形成阶段 ;陆内盆地演化阶段 ;盆山转换及推覆构造形成阶段。
The history of the formation and evolution of the Lanping basin is long and complex. The Lanping basin has undergone the process from the oceanic basin to the transformation of ocean-continent to the intra-continental basin to the transformation of basin-mountain. According to the characteristics of the basin filling and orogenic belt, this paper discusses the evolutionary process and the corresponding relation of the basin-mountain. By the analysis of the geological materials in the Lanping basin, the evolutionary process of the Lanping basin can be divided into three phases,that is, the formation of the basement of Lanping; the evolution of the intra-continental basin and the transformation of the basin-mountain.
