The balance between nucleation and growth determines the overall grain size and grain size distribution in the rock. If we know something about the relative magnitudes of interfacial energies we can make predictions about what these microstructures look like and therefore predict how fluids move through the Earth.
General sources Crystal nucleation and growth Topics covered in this introduction include nucleation (homogenous and heterogeneous, including the effects of pore size in nucleation inhibition) and crystal growth mechanisms. Chapter 4 (B 30.107 or on Moodle) Morphology Textural equilibrium Once reaction is over, and if the rock is not being deformed rapidly, microstructures evolve towards a minimum energy state, in which grain shape and the topology of minor phases (such as fluid) are controlled by interfacial energies.

The classic Skaergaard intrusion is the one that started it all (and incidentally resulted in a hiatus in our developing understanding of magma plumbing systems as it is so iconic that no-one could imagine anything looking or behaving different to Skaergaard), forming from closed-system fractionation.
