Crystal formation types
Webigneous rock, any of various crystalline or glassy rocks formed by the cooling and solidification of molten earth material. Igneous rocks constitute one of the three principal classes of rocks, the others being metamorphic … WebHence the process of crystal formation is spontaneous below the equilibrium melting point(Tm ∞)∗∗ while the reverse process, i.e. crystal melting to form liquid is spontaneous above Tm ∞. At T m ∞, a condition of equilibrium exists between the crystal and liquid as both phases have the same value of G and ∆G= 0.
