CONCENTRATION INTRODUCTION During the crystallisation of a magmatic meltmany minerals of economic value also get formed depending on the original composition of the melt These minerals may get concentrated towards the bottom or margins or other places within the cooling body of magma because of some factors operating at the time of . fronts and magmatic evolution D.
