Fracture induced emission of alkali atoms from feldspar

Emission of neutral atoms (K and Na) and molecules (H2O and KOH) observed during fracture of K-feldspar have been accounted for by two independent mechanisms. H2O and KOH emissions are attributed to the venting of fluid-filled inclusions, while emission of atomic K is due to surface effects accompanying cleavage of crystalline feldspar.
