Previously, late Paleozoic deformation of the Antler orogen has been referred to as the Humboldt orogeny (Ketner, 1977), and the Humboldt orogeny was envisioned mainly as including late Paleozoic epeirogenic uplift, as well as depression of a number of basins widespread throughout the Cordillera (Snyder and others, 2000).

The deposition of this sequence followed the Antler Orogeny and associated movement on the Roberts Mountains Thrust. The sediments of the Overlap Assemblage were derived from the Antler Highland which was formed as a result of the imbrication of the Roberts Mountain Allochthon. iv).Antler Orogeny.

That was followed by the even more controversial Sonoma orogeny which may have occurred as late as the early Triassic. Evidence for both the Antler and Sonoma orogenies is only found in Nevada. The Antler orogeny was a volcanic island arc that was accreted onto western North America with the subduction direction away from North America.

It was a pretty long-lived event as it lasted until the Pennsylvanian. The Orogeny was caused by a collision of an island arc. This might strike you as a bit surprising considering that I just stated that western ... ku game tonight But to the west the rocks are more siliceous, those coarse conglomerates, and there are some interbedded volcanic rocks. The western rocks are thrust eastward on top of the eastern rocks in the Roberts Mountains Thrust Fault, a major feature which is additional evidence for the tectonic activity we call the Antler Orogeny.Terranes started to collide with the western edge of North America in the Mississippian age (approximately 350 million years ago), causing the Antler orogeny. During the last half of the Mesozoic Era, much of today's California, British Columbia, Oregon, and Washington were added to North America.
