粗面玄武岩

岩石类型包括粗面玄武岩、玄武粗安岩、粗安岩等，岩石化学和岩石系列特征表明，其形成的构造环境为陆内造山带。

The rock types include trachybasalt , basaltic trachyandesite and trachyandesite . Their characteristics of petrochemistry and rock series indicate that the volcanic rock was formed in intra continental orogenic belt .

粗面玄武岩榴辉岩相变过程中的石榴石生长速率大于安山岩榴辉岩相变过程中的石榴石生长速率，实验样品的初始化学成分及挥发份含量的不同造成了这一差别。

However , the rate of the garnet growth during the trachybasalt eclogite transformation is more rapid than that of the garnet growth during the andesite eclogite transformation . This phenomenon is attributed to the differences of the chemical compositions and the volatile contents between the trachybasalt and the andesite .

火山熔岩类主要包括玄武岩、粗面玄武岩、气孔杏仁状安山岩、粗面安山岩、流纹岩等。

The lavas mainly include basalt , dolerite , fumarolic , amygdaloidal andesite , trachy-andesite and as well as rhyolite .
