兰坪思茅地洼盆地的特征及与中国东部地洼盆地的对比

兰坪思茅拉张型地洼盆地处于亚洲复式壳体南部东亚壳体、中亚壳体和南亚壳体接合部位，其形成的背景及演化的历史比较复杂。对比分析表明：其构造格局、沉积作用、火山作用及成矿作用与中国东部的地洼盆地差异明显。研究表明造成这种复杂差异性的原因，是组成滇西壳体构造地幔蠕动的方式及作用不一，与诸壳体演化历史差异、壳体之间汇聚拼合方式及运动形式的不同有关。

CHARACTERISTICS OF LANPING-SIMAO DIWA BASIN AND COMPARISON WITH OTHER DIWA BASINS IN EAST CHINA

Lanping-Simao tensile-type diwa basin,situated at the triple-junction of East Asia,Central Asia and South Asia crustobodies within the south part of Asia complex crustobody,is characterized by intricate forming background and evolution history.Comparative study of Lanping-Simao basin with other diwa basis in East China shows that the basin possesses distinct peculiarities of tectonic framework,sedimentation,volcanism and mineralization.This distinction is to the difference in mode and process of mantle creep in western Yunnan,in evolutionary history and convergent way of crustobodies.
