This observation prompted a conclusion that the Appalachian synorogenic clastic wedges commonly have detrital-zircon age populations that are one orogeny behind (Thomas et al., 2004), suggesting that erosional unroofing of synorogenic zircon-yielding rocks was not far enough advanced to include those zircons in the detritus (indicating a …High-resolution stratigraphic studies in the Diamond Mountains are revealing details of tectonic deformation and basin filling that post-date the emplacement of the Antler allochthon and predate the Sonoma orogeny. Antler foreland-basin strata were deformed, uplifted, and eroded in the middle Mississippian, and a late Mississippian successor ...

For the purposes of geology, the "calendar" is the geologic time scale. One way to distinguish and define each segment of time is by the occurrence of major geologic events and the appearance (and disappearance) of significant life-forms, starting with the formation of Earth's crust followed by the appearance of ever-changing forms of ...

The Antler orogeny was a tectonic event that began in the early Late Devonian with widespread effects continuing into the Mississippian and early Pennsylvanian.

The Antler orogeny resulted from late Middle Mississippian sinistral-oblique convergence at this step. Continuing oblique convergence produced the subsequent late Paleozoic basins, structures, and unconformities in northern Nevada. The Roberts Mountains allochthon is translated material from farther north emplaced onto the margin.

The Antler Orogeny, named by geologists in 1951 after Antler Peak on Battle Mountain, was an early orogeny mountain building event in the creation of the Basin and Range Province. The Antler highland, including the Roberts Mountains, formed as fractured deep ocean sediments were thrust upward.
