| 摘 要： | 分析了赣南—粤北中生代晚期火山岩系划分的现状和存在的问题，提出以火山旋回、火山—沉积复合岩相为划分依据，划分为３ 群６ 组：形成于中侏罗世的下火山岩系称为余田群，下分水头迳组和菖蒲组；形成于晚侏罗世的中火山岩系称为莲花寨群，下分上丁组和鸡笼嶂组；形成于早白垩世—晚白垩世早期的上火山岩系称为版石群，下分合水组和优胜组。

| Abstract: | The subdivision of the late Mesozoic volcanic sequence is reviewed and relevant problems proposed.It is suggested that on the basis of volcanic cycle and sedimentary facies,the sequence could be subdivided into three groups and six formations.The volcanics in the bottom of mid Jurassic are named as Yutian Group,which is subdivided into Shuitoujing and Changpu Formation.The volcanics in the middle of late Jurassic are named as Lianhuazhai Group that could be subdivided into Shangding and Jilongzhang Formation.The volcanics in the upper portion of the Cretaceous are named as Banshi Group that is further divided into Heshui and Yousheng Formation. |
