| Host rock: | Roberts Mountains Formation |
| Host type: | Limestone |
| Structure: | Decalcified, 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. |
| Alteration processes: | Alteration types consist of silicification and clay alteration. At 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. |
