摘要
笔者详细研究了剑川-马登、鹤庆-甸南碱性的火山岩系、火山学、岩石学、岩石化学及同位素特征,并对剑川城西之火山岩岩相进行了划分。提出剑川-马登、鹤庆-甸南之火山岩有同源性, 是上地幔橄榄岩局部熔融并运移至壳幔混合层, 经改造形成富碱岩浆房, 喷出地表 (侵入) 形成。
We have a study in details on the volcanology, petrology, petrochemistry and isotope characteristics of the alkalic volcanic rock series in Jianchuan-Madeng and Heqing-Diannan and a lithofacies division of the volcanic rocks west of Jianchuan town. And we think the volcanic rocks in Jianchuan-Madeng and Heqing-Diannan are cogenetic, formed by the eruption of alkaline magma resulted from the peridotite of upper mantle, which has been partially melted, moved to thd mixed horizon of mantle and crust and reformed.
