摘要
在广泛搜集闽浙赣地区中生代陆相火山岩系同位素年龄资料的基础上 ,通过对中生代陆相火山岩系的层序及其广泛分布全区的标志性地层 (碳酸岩层 )、旋辶回 划分和对比 ,建立了三省区中生代陆相火山岩系的综合性拼接剖面 ,阐明中生代陆相火山活动的历史 。
Based on the isotopic age data of Mesozoic terrigenous volcanic series in Fujian, Zhejiang and Jiangxi Provinces, the classification and correlation of the lithostratigraphic sequence, indicator strata (carbonate layer) and structural cycles of Mesozoic terrigenous volcanic series, a comprehensive amalgamation profile of Mesozoic terrigenous volcanic series within the three Provinces has been built up, which can clarify the history of Mesozoic terrigenous volcanic activities. According to the profile, it can found out the characteristics of the inverse evolution of Mesozoic volcanoes and magma.
