On west side of mountain.
Structure: Low Angle Faults; Thrust Fault; NNW-Trending Folds

Alteration: Silication

Deposit: Workings occur along a brecciated zone bedding in bleached,recrystalized dolomite. Lamprophyre dikes cut the section, causing silication near their contact zones. The bedding-controlled mineralization exposed in the upper stope shows crusts and fillings of mno and cu oxides which also fill around and between blocks of delomite. Dolomite blocks are recrystallized;wollastonite occurs As rims on the block, and the oxide minerals intermix with the and coat the wollastonite. Minerals noted are Mn oxides, morphite, aurichalcite,malachite, calcite,wollastonite, ceragyrite?argentite? contact zone along edge of lone mountain pluton is 0.5 mile wide.

Deposit type: Polymetallic replacement

Development: Inactive at time of examination in 1983

Neogene
2.588 - 23.03 Ma



ID: 3186305
Cenozoic volcanic rocks

Age: Neogene (2.588 - 23.03 Ma)

Stratigraphic Name: Columbia River Basalt

Comments: Columbia Plateau

Lithology: Flood basalt(s); mafic volcanic rocks; basalt

Reference: Chorlton, L.B. Generalized geology of the world: bedrock domains and major faults in GIS format: a small-scale world geology map with an extended geological attribute database. doi: 10.4095/223767. Geological Survey of Canada, Open File 5529. [154]

Early Cambrian - Neoproterozoic
511 - 1000 Ma



ID: 2846442
Crossbedded quartzite, siltstone, and phyllite

Age: Neoproterozoic to Cambrian (511 - 1000 Ma)

Stratigraphic Name: Campito Formation; Deep Spring Formation; Harkless Formation; Poleta Formation; Reed Dolomite; Gold Hill Formation; Osgood Mountain Quartzite; Prospect Mountain Quartzite; Stirling Quartzite; Wood Canyon Formation; Zabriskie Quartzite

Description: These lowermost Cambrian to Precambrian strata are scattered over much of central and eastern Nevada and form the base of the Phanerozoic part of the continental margin stratigraphic section. They include the Campito, Deep Spring, Harkless, and Poleta Formations, and the Reed Dolomite in Esmeralda County; the Gold Hill Formation in northern Nye County; unnamed quartzite and shale in White Pine County; the Osgood Mountain quartzite in Humboldt County; the Prospect Mountain Quartzite in northern Nye, Lincoln, Eureka, and Elko Counties; unnamed quartzite and shale in Lander and Clark counties; and the Stirling Quartzite, Wood Canyon Formation, and Zabriskie Quartzite in southern Nye County. In a number of places, these rocks are depositional on Late Proterozoic unit Zqs. In southernmost Clark County, CZq is lying unconformably directly on Early Proterozoic gneiss (Xm). In the east-central part of Nevada, CZq is overlain depositionally by Cambrian carbonate (Cc) of the Carbonate shelf sequence. In the Nolan belt, these rocks are depositionally overlain by unit Ctd. In the Osgood Mountains in Humboldt County, Permian and Pennsylvanian rocks of the Siliciclastic overlap assemblage (PIPacl, Pacl) rest unconformably directly on the Osgood Mountain Quartzite.
