摘要
赣南—粤北白垩纪火山杂岩以合水组和优胜组为代表，其中合水组为一套夹玄武岩的沉积岩的组合岩，优胜组为一套酸性火山岩的组合岩。本文在讨论白垩纪火山杂岩岩石学和岩石化学特征的基础上，对火山杂岩的构造环境和成因机制作了分析。
The Heshui formation and Yousheng formation are typical stratum for Cretaceous volcanic complex in south Jiangxi and north Guangdong area. The Heshui formation is a sedimentary rock association which contains basalt interlayer, and the youheng formation is a acidic volcanic rock association. This paper analyses the tectonic environment and genetic mechanism for volcanic complex after discussing the petrology and petrochemistry characteristics of Cretaceous volcanic complex.
