CHEMICAL ANALYSIS OF MINERALS

photons are emitted as outer shell electrons drop to inner orbitals. 3) Photons have characteristic energies and elemental concentrations can be calculated with this technique by comparing sample intensities to a know standard. XRF can analyze most elements heavier than oxygen (though there can be some complicating factors) down to the ppm level.

Fracture induced emission of alkali atoms from feldspar ...

Emission of neutral atoms (K and Na) and molecules (H 2 O and KOH) observed during fracture of K-feldspar have been accounted for by two independent mechanisms. H 2 O 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. The intensity of emitted

Feldspar in type 4–6 ordinary chondrites: Metamorphic ...

Abstract– We have carried out a study of feldspar compositions in a suite of H and LL ordinary chondrites, of petrologic types 4, 5, and 6, in order to examine the process of recrystallization and equilibration of feldspar as the degree of metamorphism increases. In the H chondrites, there is little variation in feldspar compositions among the petrologic types, suggesting that
