Abstract

Deformation bands were analyzed by mapping and describing over 500 of the structures exposed on a bedding surface of about 560 square meters present in the Aztec Sandstone in the Valley of Fire State Park, Nevada; Three sets of deformation bands are present. Two sets are interpreted as coeval and form a conjugate set with a dihedral angle of 90 degRees These are often composed of multiple bands. In contrast, the third set is nearly always a single band which is sinuous or jagged along its length. They often curve sharply near the intersections with the earlier formed sets, becoming parallel rather than intersecting the other sets. Despite this sinuosity, these bands have consistent orientations and are parallel with each other from end to end; Relationships with other structures in the vicinity suggests deformation bands formed in response to regional compression.
