Abstract

The nucleation of diopside and anorthite is always delayed under supercooled conditions. The delay in nucleation decreases with increasing degree of supercooling or increasing cooling rate. With further increase in the degree of supercooling or the cooling rate, the delay in anorthite nucleation increases. For a given degree of supercooling, the region of random nucleation of diopside is wider than that of anorthite. Steady-state nucleation occurs for diopside and transient nucleation for anorthite.--Modified journal abstract.
