Multicomponent diffusion in ionic crystals: theoretical model …
Given the predominance of (^{39}) K in natural alkali feldspar and the reversed relative K isotope abundances in the KCl salt, where (^{41}) K is the majority K isotope, the salt acted as a source for the in-diffusion of (^{41}) K from the salt into the feldspar and as a sink for (^{39}) K and (^{23}) Na driving the out-diffusion of ...

Feldspar Chemical Composition
Feldspar exhibits two directions of perfect cleavage that intersect at or close to ninety degrees. Feldspar minerals (natural mineral) have a Mohs hardness of around 6 to 6.5. The specific gravity of feldspar mineral is between 2.5 and 2.8. Feldspar minerals (natural mineral) have a vitreous lustre, this lusture is often pearly on cleavage faces.

Physical properties of feldspar minerals: Feldspar minerals have amazingly consistent physical properties. Most of the minerals in the feldspar have two courses of good cleavage that converge at nearly right angles. Along with having the same inclination angle for their cleavages, they also possess the same specific gravity and Mohs firmness.

Applications of Pb isotopes in granite K-feldspar and Pb …
The Archean granites of the Yilgarn Craton represent an advantageous sampling medium for several reasons. Firstly, granites are a very direct link to crust-forming processes in general, and they occur in large volumes (Zartman and Wasserburg, 1969, Champion, 2013, Johnson et al., 2017, Halla, 2018).Secondly, K-feldspar is a prevalent …
