Based on plentiful isotopic dating data and geological studies, the authors, in this paper, discuss the geological meanings of the two isotopic ages given by Lapierre et al., and conclude:① Mesozoic volcanic activities in Zhejiang are most frequent in 130～83 Ma, that is, from the early to late Cretaceous but not the late Jurassic;② The Jiande and Moshishan groups are nearly in the same period and not in an upper—lower stratigraphic relationship with each other;③ The period of 110～100 Ma is a transitional stage from the early high-K calc-alkaline dacite—rhyolite associated with diorite—granodiorite） to the late basalt—rhyolite（associated with K-feldspar granite—alkali granite）.

本文就Lapierre等文中124 Ma和97 Ma两个年龄的地质意义、幕次划分以及浙西与浙东火山岩时代对比作出评论，并厘定浙江中生代火山岩时代归属，提出：①浙江中生代火山活动时代为132～83 Ma；②浙西建德群与浙东磨石山群火山岩并不存在上下关系，地质接触关系、古生物组合和大量同位素定年数据都不支持Lapierre等的浙西与浙东火山活动幕次的对比方案；③ 110～100 Ma为早期高钾钙碱性英安岩—流纹岩（伴生闪长岩—花岗闪长岩）向晚期玄武岩—流纹岩（伴生钾长花岗岩—碱性花岗岩）过渡的转折期。
