Geology
Host rockLimestone · Roberts Mountains Formation
StructureDecalcified, silty limestone units of the Siluro- Devonian Roberts Mountains Formation are folded into a northeast- trending anticline in the Chukar footwall deposit., The Roberts Mountains Thrust, Good Hope Fault System, Gold Quarry Fault, and other faults created a pervasive fracture system at Gold Quarry. Isoclinal folding of bedding is common.
AlterationAlteration types consist of silicification and clay alteration.\nAt the Gold Quarry deposit, in the central Carlin trend, Heitt (1992) reported K/Ar dates ranging from 28 to 27 Ma from supergene alunite veins that crosscut and postdate gold mineralization.
