- n. See alaskaite.
- n. In petrography, a name proposed by Spurr (1900) for igneous rocks composed almost wholly of alkalic feldspar and quartz without other essential minerals.
Sorry, no etymologies found.
At Empire, Colorado, one of the principal producing localities, it is found in veins, associated with pyrite, and filling the interstices between brecciated fragments of a wall rock composed of alaskite (an acid igneous rock).
Gold mineralization at Mineral Ridge and the adjacent areas is hosted by localized pegmatitic alaskite and accessory quartz veins that exist near a granite-metasediment contact.
This mineralization occurs at or near a shallow dipping contact between alaskite, rhyolite breccia and Luning limestone approximately 40 feet below the old 353 ft. level and above the 500 ft.
Peter McIntyre, Extract Resources MD, is on record as saying "Rössing South is the first new alaskite-hosted uranium discovery in Namibia in many years and is shaping up as the most significant discovery since the SJ deposit at the Rössing Mine".

Hole BD-08-37 was a vertical drill hole that collared into andesite at 15. 30m followed by intercalated andesite and alaskite through to 163. 00m.
- 467. 00m with minor intercalated alaskite throughout before intersecting the quartz feldspar porphyry.
