Develop a conceptual model to explain the exposed rocks.
Although commonly obscured by simple shear, pure shear fabrics occur locally within many metamorphic core complexes. The cover rocks of the Raft River metamorphic core complex exposed within the Black Pine Mountains display an early coaxial strain history which developed prior to the formation of low-angle fault-bounded allochthons. At higher structural levels this is documented by pressure shadows with straight sutures, and oppositely-rotated antitaxial calcite veins.
