闽浙赣粤中生代晚期火山岩岩石地层划分综述

Summary for the Lithostratigraphic Division of the West Zone of Volcanic Rock Petrographic Province in Late Mesozoic in Fujian, Zhejiang, Jiangxi, and Guangdong Province

将闽浙赣粤中生代晚期火山岩西区带分为江南区、武夷区和南岭区三个构造—岩浆活动区。根据岩性岩相特征 ,结合岩石地层单位群与火山旋回或沉积旋回相对应的原则 ,将江南区划分为两个群 ,武夷区划分为三个群 ,南岭区划分为四个群。根据组与火山 -沉积复合岩相或沉积岩相相对应的原则 ,各群又可进一步划分为若干个组。

The west zone of volcanic rock petrographic province in late Mesozoic in Fujian, Zhejiang, Jiangxi, and guangdong province can be divided into Jiangnan, Wuyi and Nanling tectonomagmatic activity regions. According to the characteristics of lithology and lithofacies, the principle that lithostratic unit group is related to volcano cycle or sedimentary cycle, Jiangnan region can be divided into two groups, Wuyi region can be divided into three groups, Nanling region can be divided into four groups. These groups can be further divided into formations according to the principle that formation is related to volcanic sedimentary lithofacies or sedimentary lithofacies,
