I99 x.4. Calculate FeO (T) and Fe,O.(T) for a rock having 9.15% FeO and 3.47 % Fe,O ns. lo calculate FeO (T), keep the FeO wt.% as it is, convert the Fe,O, wt.% into FeO wt.%, and then add the two. i.e., FeO (T) = 9.15 + (3.47 x 0.8998) = 12.27 wt.%. To calculate Fe,O, (T), keep the Fe,O, wt.% as is, convert the FeO wt.% into Fe,O, wt.%, and then add the two. i.e., Fe,O, (T) = 3.47 + (9.15 x 1.1113) = 13.63 wt.%. Thus, FeO (T) and Fe,O, (T) for the same rock have different values. Also, both values are different from the simple sum of FeO% and Fe,O,%, which is 12.62 wt.9%. nhaca nile the maximum number of phases in a 2 (two) component geological system
