1997-2-4  Crystallization of plagioclase from a melt or molten rock magma has been studied in detail. As the melt cools, the feldspar that forms is richer in calcium than the melt itself. On further cooling, feldspar that is richer in sodium forms, and the feldspar already formed tends to react with the melt and become richer in sodium as well.

What is Mica? How is Mica Formed? What is it is Used

How is Mica Formed? Micas do originate as a result of diverse processes and several conditions. There are various processes of formation that includes deposition by fluids derived from magmatic activities, consolidating magmas, deposition of fluid circulating by both contact and regional metamorphism, and also by alternate process. They are even caused by weathering of feldspar and minerals.
