Information leading to the delineation of this focus area

Basis for focus area Outline of Granite Peak district from Krahulec (2018b). Minor historical production of fluorite and known occurrences of beryl.
Identified resources Historical production of fluorite, lead, and silver.
Production Minor.
Status Past mining.
Estimated resources Unknown.
Geologic maps Hintze (1980), scale 1:500,000; Clark and others (2009), scale 1:24,000.
Geophysical data Inadequate Rank 4 aeromagnetic coverage.
Favorable rocks and structures Foliated granodiorite underlain by a less strained and more leucocratic granite. Both intrusive phases are cut by pegmatite and aplite dikes and quartz veins. The pegmatite dikes typically strike approximately N. 35° E. and dip 55° to 70° W (Krahulec, 2018b).
Deposits El Dorado, Desert Queen (MRDS dep_id: 10015185).
Evidence from mineral occurrences MRDS, UMOS (Utah Geological Survey, 2021).
Geochemical evidence Beryl and fluorite occurrences.
Geophysical evidence Unknown.
Evidence from other sources See Krahulec (2018b); Clark and others (2009).
Comments No public access (Dugway Proving Ground). Enrichment of many critical commodities (for example, Bi, Nb, Sc, Ta, Sn, and W) are inferred from the mineral system/deposit type table (Hofstra and Kreiner, 2020). More work is required to verify the presence/absence of enrichment of these critical commodities in the area.
Cover thickness and description Unknown.
