认为火山岩的成分分异受斜长石在岩浆源区熔融残留和岩浆形成后黑云母的结晶分离双重控制。
The chemical variation of the volcanics are controlled by both residual of plagioclase in the melting source area and crystal fractionation of biotite after magma formation.
因此，岩浆起源于加厚地壳底部榴辉岩相镁铁质岩石的低度部分熔融，且岩浆源区受到了流体的影响。
Therefore, the magmas were the product of low partial melting of mafic eclogite at the base of the thickened crust, and their magma sources were affected by fluids.
元素地球化学分析表明火山岩系具有同一岩浆源区，其形成以部分熔融方式为主。
Based on the analysis of element geochemistry, the volcanic rock series have same magma source and the formation of the rocks is mainly in the form of partial melting.
