A porphyritic texture where large crystals are embedded in a matrix of small crystal
may form when
a magma that has partially crystallized slowly moves to a different location where it
then cools rapidly.
climate change causes crystals to cool at different rates
crystals of different compositions grow to different sizes
crystals of different compositions cool at different rates
