Paragonite

The Na + ions released from the alteration of the sodic ash made the kaolinite transform into paragonite , forming the special mineral assemblage in both of them .

在蚀变过程中析出的部分Na＋离子，促使高岭石向钠云母转化，形成了高岭石加钠云母的特殊组合。

The mineral assemblages in the main stage are garnet + phengite + quartz + magnetite ± paragonite ± epidote / zoisite in the mica schist ;

主期阶段的矿物组合在云母片岩中为石榴石＋多硅白云母＋石英＋磁铁矿±钠云母±绿帘石／黝帘石；
