Fig. 12From: Diffusion-controlled growth and degree of disequilibrium of garnet porphyroblasts: is diffusion-controlled growth of porphyroblasts common?Relative growth rate of a sphere perturbation relative to the growth rate of a sphere. The relative growth rate ((dδ l /dt)/(dR g /dt)) is a function of wavelength λ l . The relative growth rate is calculated using Eqs. 6, 9 , 10, and 11, with Γ D = 1.58 × 10−5 mm, R g = 644 μm, and Δζ = 0.05 × 10−1–0.3Back to article page
