Named; no type area designated; derivation of name not given. [Probably named for Santa Catalina Mountains and is presumably intended as an informal lithodemic unit.] Occurs in northwestern Santa Catalina and southern Tortolita, and eastern Rincon Mountains, Pinal and Pima Cos, AZ (Basin-and-Range province). Consists of one granite and three quartz monzonite plutons, which are, Reef of Rock granite and Catalina, Tortolita, and provisionally, Happy Valley quartz monzonites. Tortolita pluton intrudes Catalina pluton. Catalina suite is one of three post-Paleozoic suites of intrusive bodies in Santa Catalina-Rincon-Tortolita crystalline complex of southeastern AZ (others are Leatherwood and Wilderness suites). Suite is mineralogically distinct from Wilderness and Leatherwood (modal analyses reported in table 5). Discussion of nomenclature (appendix 1). Isotopic age data indicate a late Oligocene and early Miocene age for Catalina suite.
