A geologist defines a mineral as a solid formed by natural processes that has a crystalline structure — a unique arrangement of atoms — and a definable chemical composition. Minerals are the basic geological building blocks of the solid earth; they combine in different ways to make many types of rocks.

Thus, some minerals show complete solid solution under one set of temperature/pressure conditions, and only limited solid solution under different temperature/pressure conditions. When the conditions change to those where limited solid solution is favored, the mineral exsolves or unmixes.
