• Buddingtonite - Wikipedia

    en.wikipedia.org/wiki/Buddingtonite Buddingtonite is an ammonium feldspar with formula: NH 4 AlSi 3 O 8 (note: some sources add 0.5H 2 O to the formula). It forms by hydrothermal alteration of primary feldspar minerals. It is an indicator of possible gold and silver deposits, as they can become concentrated by hydrothermal processes.It crystallizes in the monoclinic crystal system and is colorless to white with a vitreous luster.

Buddingtonite is the ammonia feldspar originally found at this locality as a low temperation hydrothermal replacement of plagioclase from ammonia bearing hot springs. It has since been found in the Phosphoria formation of Idaho, and in metasomatized rhylolitic ash-flows tuffs in the Cedar Mountains of Nevada.
