对皖西大别山太湖榴辉岩中的石榴子石（Ｇｔ）、单斜辉石（Ｃｐｘ）、角闪石（Ｈｂ）、蓝晶石（Ｋｙ）、斜长石（Ｐｌ）和方解石（Ｃｃ）等变质矿物进行了矿物共生分析，认为该区矿物共生组合的存在及其变化主要取决于钾钠化学位和温度、压力的变化，在榴辉岩向榴闪岩退变质转化过程中钠交代和温压的降低是重要的物理化学条件。
(Gt), Cpx, Hb, Ky, plagioclase (Pl) and calcite (Cc) in the Taihu eclogites of the Dabie Mountains in western Anhui Province, And other metamorphic minerals were analyzed. It is concluded that the existence and the change of mineral assemblages in this area mainly depend on the change of potassium-sodium chemical position, temperature and pressure. During the conversion of eclogite to metamorphic metamorphic rocks, The decrease of temperature and pressure is an important physicochemical condition.
