The Metamorphic Mineral Assemblages of Eclogite in Taihu Area of Dabie Mountains

大别山太湖榴辉岩变质矿物共生分析

A lot of high pressure metamorphic mineral glaucophanes have been discovered in the green schist .

绿片岩中发现较多蓝闪石高压变质矿物；

It exists clear differencees in metamorphic mineral assemblages and structure feature between UHP metamorphic complex and granitic gneisses , showing the difference in metamorphic condition and process between them .

南大别山超高压变质杂岩与花岗片麻岩具有不同的变质矿物组合和结构特征，显示它们之间变质作用条件和过程可能存在着差异。

Based on carbonate geothermometry dolomite 1 crystallization occurred at 300-340 ℃, which is supported by the M1 metamorphic mineral assemblage ( chlorite , muscovite-illite ) .

根据碳酸盐矿物对地质温度计，白云石1结晶作用发生在300~340℃。

There is just the striking evidence that the penetrative schistosity exists everywhere in mountain making belts , which is formed by the parallel directive arrangement of syntectonic metamorphic mineral assemblage .

在造山带内，由同构造变质矿物组合方向性平行排列构成的片理，就是显著的证据。

According to the appearence of characteristic metamorphic mineral and the relation of distribution of Mg in garnet-biotite to temperature , the metamorphic temperature is about 550 & 700 ℃ , the pressure is about 400-800 MPa .

同时，根据特征变质矿物的出现及镁在石榴石-黑云母矿物对的分配与温度的关系计算，变质温度为550700℃，压力为400800MPa，相当于中压角闪岩相。

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 .

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。
