The Ray mine, a porphyry copper deposit north of Tucson, is highly dismembered by Cenozoic normal faults. This study revises the interpretation of those faults after a comprehensive compilation of previous and recently acquired information. Laramide reverse faults are not recognized, but five sets of normal faults were identified: faults of set 1 are apparent reverse (older on younger relations) faults; sets 2-3 also are normal faults associated with mid-Cenozoic extension; and sets 4-5 are associated with late Cenozoic extension. Faults of sets 1-5 are responsible for post-mineralization tilting and dismemberment. Sets 2-5 structure might have played a role in the formation of secondary copper mineral assemblagesType
