(Table 6) Representative analyes of phengite, chlorite, albite, and sphene of...

Calculation base on O = 22 (phengite), O = 28 (chlorite), O = 8 (albite), Si = 4 (sphene). Total Fe as FeO or Fe2O3.本计算基于如下基准：氧原子数（O）为22对应多硅白云母（phengite）、O=28对应绿泥石（chlorite）、O=8对应钠长石（albite），硅原子数（Si）为4对应榍石（sphene）；全铁以FeO或Fe₂O₃形式计。
