A basaltic magma has an initial nickel concentration of 300 ppm
Q. A basaltic magma has an initial nickel concentration of 300 ppm. Olivine crystallizes from this magma by equilibrium crystallization (Case I) or fractional crystallization (Case II). Then, the absolute value of the difference between the nickel concentrations of the liquids remaining after 25% crystallization in these two cases is.(Use KD,Ni olivine/melt = 10).
