Geology

Host rock:	Roberts Mountains Formation;Popovich Formation;Rodeo Creek Unit;Vinini Formation;Roberts Mountains Formation;Roberts Mountains Formation
Host type:	Dolomite
Associated rock:	Unknown;Unknown;Unknown;Unknown;Unknown
Associated type:	Rhyolite
Structure:	Carlin Trend, Nnw-Striking. Carlin Occurs In The Lynn Window Of The Roberts Mountains Thrust. Some Workers Believe The Windows In The Thrust Are Due To Doming Of The Paleozoic Sediments By Intrusions At Depth. Carlin Lies Near The Crest Of The N-Nw Striking Tuscarora Mountains Anticline. The Regional Scale Leeville Fault System Consists Of Numerous High Angle Fault Strands That Strike Nnw And Form An Important Ore-Controlling Feature Along The Eastern Edge Of Mineralization., Three Sets Of High Angle Normal Faults Are Recognized. In Order Of Oldest To Youngest, Their Attitudes Are 1) N60-80w, Dipping Steeply North, 2) N45w To N-S, Dipping In Either Direction From 60 Degrees To Vertical, 3) N40-60e, Dipping 50-80 Degrees Either Nw Or Se. The Third (Youngest) Set Of Faults Have Very Minor Offsets And May Best Be Described As Zones Of Shearing Or Rock Shattering. Igneous Dikes Of Intermediate Composition Have Been Emplaced Along Some Faults.
Tectonic:	Antler Belt
Alteration processes:	Decarbonitization, Silicification, Argillization. See Geology Comments.
