福建中生代火山活动经历晚三叠世—早侏罗世的初始，晚侏罗世的鼎盛及白垩纪的减弱、衰亡3个发展阶段；3个阶段的火山活动特征、岩石组合、岩石化学及地球化学等方面既有明显的差异，又具有过渡演化趋势，是受同一构造机制作用而发生与发展。研究认为，福建中生代火山岩的形成与太平洋板块向欧亚大陆板块俯冲作用密切相关，可谓之“浙闽型火山岩”。

Mesozoic volcanic activities experienced three stages, namely theLate Triassic_Late Jurassic initial stage, the Late Jurassic flourishing stage and the Cretaceous weakening_withering stage. The three stages, controlled by the same tectonic mechanism, show remarkable differences and also transitional characteristics in such aspects as volcanic activities, rock assemblages, petrochemistry and geochemistry. Studies show that the formation of Mesozoic volcanic rocks was intimately related to the subduction of the Pacific plate towards the Eurasian plate, and these volcanic rocks can be called Zhejiang_Fujian type volcanic rocks.
