The research results indicate that the volcanic rocks in the studied abea are composed of two different kinds of association: Tholeiitic series and calc-alkaline series (basalt, andenite, dacite and rhyolite ).

结果表明，研究区火山岩由拉斑系列大洋玄武岩和钙碱性系列岛弧玄武岩、玄武安山岩、安山岩、英安岩和流纹岩组成。

Volcanic gas reservoirs of low permeability in the carboniferous of a basin are characterized by deep burial depth, complex genesis, many types, wide distribution and non-evident expressions in three-porosity log curves, as well as the variedvalues of density and compression wave of main four volcanic gas reservoirs (such as the basalt, andesite, dacite and rhyolite). So a number of effective methods based on three porosity log data cannot work in identifying the volcanic gas reservoirs of the carboniferous of the basin.

石炭系火山岩的低渗透气藏具有的埋藏深、成因复杂、类型多、分布广、三孔隙度曲线响应特征不明显等特点，并且主要的四种火山岩气藏：玄武岩、安山岩、英安岩、流纹岩的密度和纵波时差测井值差别较大，因此使基于三孔隙度测井资料的一系列识别气层的有效方法在该盆地石炭系火山岩气层的识别中无明显效果。

Firstly, the volcanics and shaly sand were separated with FMI static images and conventional logging data. Then, the image characteristics of all typical volcanics were analyzed with the dynamic FMI images to establish the FMI image patterns of volcanic lava (including rhyolite, dacite, andesite, and basalt) and volcaniclastic rock (including volcanic breeds and tuff).

首先利用FMI静态图像和常规测井曲线将砂泥岩与火山岩区分开来；然后利用FMI动态图像分析了火山岩各种岩性的图像特征，归纳总结出火山熔岩类（流纹岩、英安岩、安山岩、玄武岩）和火山碎屑岩类的FMI图像模式。

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。

The rock types mainly include basalt, andesite, dacite and little rhyolites, lava breccia etc. The rocks have the following chemical composition: SiO2, 48.49%-74.52%, with a mean value of 60.87%, Al2O3 majority between 14.5%-18.86%, K2O mean contents 1.99%.

主要岩石类型为玄武岩、安山岩、英安岩及少量流纹岩、火山角砾岩等，SiO2=48.49%~74.52%，平均60.87%，Al2O3多数在14.5~18.86之间，K2O含量平均为1.99，显示钙碱性系列特征。
