| 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 |
