2 . 38 . 6ma and 36 . 7ma isotopic ages of quartz - monzonite - porphyry in lianhuashan and alkaline porphyry in zhuopan have respectively been obtained . those results are consistent with the ages of the porphyries in both lanping - shimao basin and changdu basin related igneous rocks , representing the first episode ( lanping movement ) of tectonics - magmatism - metallogenic event during the himalayan movement 获得了莲花山石英二长斑岩及卓潘碱性斑岩的ar - ar年龄，分别为38 . 6ma与36 . 7ma ，与整个兰坪?思茅盆地与昌都盆地及两侧的斑岩与相关火山岩一致，代表喜马拉雅运动第一幕(兰坪运动)的重要构造?岩浆?成矿事件。
