Information leading to the delineation of this focus area

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.
