Table 2 Radius of curvature and dominant wavelength of garnet porphyroblast interfaces, and the estimated supersaturation (Δζ)

From: Diffusion-controlled growth and degree of disequilibrium of garnet porphyroblasts: is diffusion-controlled growth of porphyroblasts common?

Garnet R g : radius (μm) a: mid-range of radius of curvature (μm) b: mid-range of dominant wavelength (μm) c: average of the dominant wavelengths by 2 × a and b (μm) Δζa lower bound calculated with value of b Δζ*a mid-range value calculated with value of c Δζ*a upper bound calculated with value of 2 × a
