The Antler orogeny occurred in Mississippian time at a passive margin of the sialic North American continent in Nevada and probably in Idaho. Its principal events were the emplacement of an extensive allochthon of oceanic rocks on the continental shelf, subsidence of an elongate foreland basin, and maintenance of highlands in the interior region of the allochthon during and after subsidence of ...The Antler Orogeny caused weak to moderate deformation in the western United States (Fig. 7.4). Parts of the Antler Orogen are now buried by younger deposits, so it is difficult to know its true geographic extent, but from the outcrops that have been identified, the Antler Orogen appears to be about 1/10 the size of the Cordilleran Orogen.

This thrusting was over the Golconda Thrust, the main trace of which ...The Antler orogeny was caused by the collision of an _____ with the cordilleran mobile belt (western Laurentia) Island Arc.
