It is argued that the magmatic activities of quartz - monzonite - porphyry and alkaline porphyry presumably played an essential role in mineralization of this district , that is , the porphyry system could be important sources of both ore - forming metals and ore - forming fluids , as well as a thermal engine that drived cycling of metallogenic fluids 初步認為石英二長斑巖與堿性斑巖巖漿活動對本區成礦有重要作用,既是重要的礦源和流體來源,又是驅動成礦流體循環的主要熱源。

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 獲得了蓮花山石英二長斑巖及卓潘堿性斑巖的ar - ar年齡,分別為38 . 6ma與36 . 7ma ,與整個蘭坪?思茅盆地與昌都盆地及兩側的斑巖與相關火山巖一致,代表喜馬拉雅運動第一幕(蘭坪運動)的重要構造?巖漿?成礦事件。
