Abstract
  • In the southern Fish Creek Range, Nye County Nevada, Devonian rocks are found overlying younger rocks. These Devonian units are allochthonous blocks that slid by gravity into their present positions. The allochthonous blocks represent several different provenances commonly found to the west and northwest of the area. The blocks include Denay Limestone, a stromatoporoid-bearing limestone, Beacon Peak Dolomite, Oxyoke Canyon Formation, and undetermined limestone and mudstone. During the Late Devonian these units were incorporated into the Roberts Mountains allochthon as it added outer-shelf carbonates then inner-shelf carbonate and clastic rocks to its base by an eastward-stepping mechanism. The Devonian blocks of the thesis area are large blocks that detached from the front of the moving Roberts Mountains allochthon and slid eastward into the Mississippian foreland trough.
