The Antler orogeny was a tectonic event that began in the early Late Devonian with widespread effects continuing into the Mississippian and early Pennsylvanian. [1 ...

The range contains rocks deformed by the Antler orogeny of Late Devonian to early Mississippian age. Along the Roberts Mountain thrust fault, which was named for the range, a terrane of oceanic island arc volcanic rocks and sediments were emplaced over the pre-existing Devonian to Silurian carbonates, sandstones and shales of the coastal margin of the continent.
Orogeny (/ ɒ ˈ r ɒ dʒ ə n i /) is a mountain-building process that takes place at a convergent plate margin when plate motion compresses the margin. An orogenic belt or orogen develops as the compressed plate crumples and is uplifted to form one or more mountain ranges .
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.
Near the end of the Devonian an interval of mountain building called the Antler Orogeny began. [2] The Antler Orogeny continued into the Early Carboniferous. Dropping sea levels exposed regions of Nevada as dry land. Environments of eastern Nevada included lagoons and beaches. Local plant life were preserved in rocks formed by these deposits.
Reindeer (also known as caribou) are a member of the deer family, native to the tundra, boreal forests, and mountains of the extreme frigid north. In human culture, they are a staple of northern ...
Terranes started to collide with the western edge of North America in the Mississippian age (approximately 350 million years ago), causing the Antler orogeny. [11] During the last half of the Mesozoic Era, much of today's California, British Columbia, Oregon, and Washington were added to North America.
