区域低温动力变质作用-
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 .

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 .
