赣南—粤北白垩纪火山杂岩来自两个不同的岩浆源区，中、基性岩类源自幔源区，酸性岩类源自壳源区，两者互有影响，组成过渡性岩浆杂岩建造，它们具有各自不同的微量元素特征。本文在讨论两个不同岩浆源区火山杂岩微量元素、稀土元素特征的基础上，对它们的岩浆源区性质进行了探讨。
The Cretaceous volcanic complexes in southern Jiangxi and northern Guangdong are derived from two different magmatic source areas. The middle and basic rock types are derived from the mantle source area and the acidic rock types are derived from the crust source area. Both of them influence each other to form a transition magma Complex construction, they have different trace element characteristics. Based on the discussion of the trace elements and rare earth elements in volcanic complexes from two different magmatic source areas, the properties of their magmatic source areas are discussed in this paper.
