| fractionation |
The process resulting from the fact that the first formed crystals in a cooling magma always have a higher ratio of Mg to Fe, of Ni to Mg, of Ca to Na, and of LILE to HFSE elements in general than the magma has. The result is a steady decrease in HFSE elements and increase in LILE as the magma cools. The amount of LILE in a magma can treble before cooling is complete.
