Crystallization Velocity Equation and Kinetics Mechanism of Plagioclase Oscillatory Zoning

This study, based on the physico\|chemistry principle, establishes the mathematics model of the genesis of plagioclase oscillatory zoning. Based on the crystal growth principle, the plagioclase crystallization velocity equation has been put forward. This equation has such a feedback character as \!supersaturation—nucleation—depletion cycle". Small\|scale oscillatory zoning is attributable to self\|organization, and has no bearing on environmental factors. Its genesis is corresponding to a relatively static environment.
