Mafic Layered Intrusions -Chromite and Platinum PGE
18/10/2015· Mafic magmas tend to be hotter and more fluid than felsic magmas and as the minerals crystallize they fall to the bottom of the melt and accumulate there, often being winnowed or sorted and eroded by currents in the magma chamber. You can see in the same picture how some of the chromite layers that outcrop appears to split or even cut out as a results of these currents. At first glance the,,,,,,
