“…Again, if a similar magnitude of 1 moveme~t is assigned to the Hidalgo thrust fault as · is here argued for the Cochise thrust fault, then tectonic transport is on the order of 200 km. This distance is remarkably similar to those proposed, on different kinds of evidence, along the Cordilleran thrust belt in Alberta (200 km or more, Price and Mountjoy, 1970), Utah (160 km or more, Stewart and Poole, 1974;or 85 km, Rubey and Hubbert, 1959;Crittenden, 1961), andsouthernNevada(36-75kmor more, Burchfiel and others, 1974;or 30-50 km, Fleck, 1970;or about 120 km, Steward and Poole, 1974). Attractive as these comparisons are, my support for such a large distance of tectonic transport is based on imperfect evidence and on projections of movement from the Cochise to the Hidalgo thrust fault.…”
