from a uniform parent magma.
The first minerals to crystallize
from a cooling magma are the
ones that are the last to melt. 3. Magmatic Differentiation
Magmatic Fractional crystallization is the
process by which the crystals
are formed in a cooling
magma and are segregated from
the remaining liquid.
Example: basaltic intrusion
like Palisades, New Jersey
