摘　　要：本文通过对庐枞巴家滩火山-侵入体的岩石化学、地球化学、O、Pb、Rb-Sr、Sm-Nd 同位素研究,运用二元混合模式、部分熔融及岩浆分离结晶过程中主量元素的定量模拟,推断出巴家滩火山-侵入体为富集型地幔来源。The petrochemistry,geochemistry and O,Pb,Pb-Sr,Sm-Nd isotopes of the Bajiatan vol-canic-intrusive complex in the Lujiang-Zhongyang area have been studied in this paper,withthe binary mixing model,partial melting and major element petrogenic-modelling of magmafractional crystallization.The results suggested that the main magma source of the Bajiatanvolcanic-intrusive complex is the enriched mantle.
