Abstract

Subsolidus marginal zoning in calcium-poor clinopyroxenes and intermediate zoning in discontinuously zoned subcalcic- to calcium-rich clinopyroxenes from ironrich igneous rocks is used to calculate the interdiffusion coefficient, DCa−(Fe,Mg), parallel to the crystallographic caxis. Wagner's mathematical models describing the displacement of interfaces in solids as the result of isothermal diffusion are adopted. The steady-state heat flow equation is used to approximate the diffusion times. The calculated interdiffusion coefficients are of a reasonable order of magnitude, viz. 6.0×10−20−2.0×10−17cm2· sec−1 at about 900° C.
