  1. 川西高原广泛分布的西康群,原视为区域低温动力变质作用低绿片岩相变质岩。

    Xikang Group is widely exposed on the West Sichuan Plateau and was considered to be a low greenschist facies metamorphic rock due to regional low-temperature dynamometamorphism .

  2. 第一期变质作用属于区域低温动力变质作用类型,以形成低绿片岩相矿物组合为特征,变质温度较低,而应力作用较强,是造山作用初期热流活动较弱,构造变形强烈环境下的产物。

    The first stage belongs to regional low-temperature dynamic metamorphic type and is characterized by typical metamorphic mineral assemblage of low greenschist facies with low metamorphic temperature and strong stress-induced recrystallization which represents weak crustal heat flow and strong structural deformation during early stage of an orogeny .
