Abstract

Two thrust faults divide the area into three distinct units: an 'autochton', which consists of clastic Mesozoic strata; the lower, or Blue Mountain, thrust plate, which is an easterly facies of the Paleozoic sequence of the eastern Great Basin and which ranges in age from Middle Cambrian to Early Pennsylvanian; and the upper or Wah Wah thrust plate, which consists of rocks of latest Precambrian to Cambrian age. The Blue Mountain thrust has a minimum horizontal displacement of nine miles. The Wah Wah, House, and Confusion Ranges are assigned to the Wah Wah thrust plate.
