... is latest Devonian to Early Permian in age, spanning the time interval from the emplacement of the Roberts Mountains allochthon onto the shelf in the earliest Mississippian Antler orogeny to the inception of the Sonoma orogeny. The history of the Schoonover basin is tied to that of the adjacent shelf...

... in the northern Sierra terrane and with Kinderhookian volcaniclastic rocks and chert in the Schoonover sequence. These quartzose-clastic deposits not only provide an independent lithologic link between the Sierran arc terrane and the Havallah basin, they also tie the arc terrane and basin to North America...

... the late Paleozoic. The Schoonover sequence represents the northernmost exposures of the Golconda allochthon, which was thrust over the outer edge of the continental margin of western North America during the Permo-Triassic Sonoma orogeny. The Schoonover sequence, like the Havallah sequence and other...

... by a cover of Miocene volcanic strata and can not be correlated on a unit-to-unit basis, but could have been deposited in the same basin. Rocks of similar provenance, age, and lithologic associations are found elsewhere in Baja California Norte, Sonora, Sinaloa, and the Havallah and Schoonover sequences...

... Mountains and Golconda allochthons, which must have formed a topographically elevated area in central Nevada during the Early Cretaceous. The stratigraphic record provides evidence of deposition in a tectonically active basin. In contrast with some prior studies inferring that deposition was synchronous...

Ore is also hosted by rhyolitic dikes that were emplaced at 40.95 ± 0.06 Ma based on zircon U-Pb chemical abrasion-thermal ionization mass spectrometry. The gold is associated with sericitic and argillic alteration...
