部分熔融：深层岩石熔融形成的岩浆不是普遍和均匀的，岩石山冷变热升温过程中，易溶组分首先熔融成为岩浆，难熔组分残留于固相。在很大的温度范围内处于平熔状态，故称部分熔融。
We suggest that the Tunchang adakitic rocks were likely generated by partial melting of newly underplated basaltic lower crust as a result of asthenosphere upwelling due to Late Early Cretaceous（107 Ma） rollback of subducted Paleo-Pacific plate.
屯昌埃达克质岩很可能由新底侵的玄武质下地壳物质部分熔融所形成,俯冲的古太平洋板块在早白垩世晚期（约107 Ma）的后撤作用所导致的软流圈上涌为地壳熔融提供了热源。

岩体所曾经受的部分熔融只发生在尖晶石或石榴石相。
The partial melting undergone by plagioclase-peridotite occurred only within spinel or garnet facies.
岩石主要由幔源岩浆与中下地壳物质部分熔融形成的花岗质岩浆的混合形成的。
They were formed by mixing of the partial melting granitic magma of crust-derived material and mantle-derived basic magma.
低ree组和高ree组煌斑岩分别是交代富集地幔约10%和4%部分熔融的产物。
Low REE group and high REE group lamprophyres are 10% and 4% partial melting of the metasomatic enriched mantle.
