Values of
Fe2O3+ (total Fe as Fe2O3) + MgO contents are between 7 and
15 wt.% for the Fat’ha Formation and between 2 and 10 wt.%
for the Injana Formation and can be classified as low to
moderate. Large-ion-lithophile (LIL) elements, such as Rb, Sr
and K, show a range of abundance. Similarly, the transition
