In 1911 Feldspar was discovered in Mitchell County, North Carolina where they became the major producer. Then, in the 1930's California became the major producer of Feldspar. Feldspar is a general name for a group of anhydrous aluminum silicate minerals which contain varying amounts of Potassium, Sodium and Calcium.
Anisotropic diffusion is described by a tensor of diffusivities, Dαβ, which may be composition dependent leading to nonlinear anisotropic diffusion. In this work the practical problem of reconstructing such a tensor for Na-K interdiffusion in potassium-rich alkali feldspar in the composition range 0.85 ≤ XOr ≤ 1.00 is addressed. Gem quality …
