Mineralogical Characterisation Of Chromite In The UG2

In this study it was found that the ug2 normal reef and the ug2 reef affected by pothole formation are both principally characterised by primary mineralogical features comprising mainly finegrained chromite as the cumulate phase and orthopyroxene and plagioclase as intercumulate phases.
