| Basis for focus area |
Lithium brine focus area based on outline of the Muddy and Lake Mead HUC8 boundaries. |
| Identified resources |
None. |
| Production |
None. |
| Status |
Exploration of brine at Jackpot Lake; inactive at Muddy Mountains. |
| Estimated resources |
Unknown. |
| Geologic maps |
Horton and others (2017), scale 1:500,000. |
| Geophysical data |
Inadequate aeromagnetic and aeroradiometric coverage. |
| Favorable rocks and structures |
The Li-enriched part of the Horse Spring Formation was formed from a series of volcanic ashes, which were deposited in a playa (Brenner-Tourtelot and Glanzman, 1978). |
| Deposits |
None. |
| Evidence from mineral occurrences |
None. |
| Geochemical evidence |
The Horse Spring Formation of Miocene age in Clark County, Nevada, contains as much as 0.5% Li in individual samples (Brenner-Tourtelot and Glanzman, 1978). Lithium-rich rocks contain low concentrations of most other minor element except B and Sr are enriched; rarely, Ba, As, and Zn are present in anomalously large amounts (Brenner-Tourtelot and Glanzman, 1978). |
| Geophysical evidence |
None. |
| Evidence from other sources |
Brenner-Tourtelot and Glanzman (1978). |
| Cover thickness and description |
Exposed at the surface. |
