...KENT C. CONDIE; G. PATRICK BOWLING; R. K. VANCE Abstract Early Proterozoic supracrustal rocks in the Dos Cabezas Mountains in southeastern Arizona include felsic volcanic and hypabyssal rocks, amphibolite, feldspathic quartzite, arkose and conglomerate, quartzite, and phyllite. Felsic volcanics...

...Floyd F. Sabins, Jr. ABSTRACT The Chiricahua and Dos Cabezas mountains are typical of the Basin-and-Range Province in southeast Arizona. Well exposed Paleozoic and Mesozoic marine strata overlie a Precambrian basement complex of schist and granite. The 7,600 feet of Paleozoic strata were deposited...

...FLOYD F SABINS, JR. Abstract The area of this report includes parts of the Chiricahua and the Dos Cabezas Mountains which together constitute a typical range in the Mexican Highland section of the Basin and Range province. The Precambrian basement complex consists of the Pinal Schist...

To support their argument, Favorito and Seedorff (2022) presented structurally restored cross-sections from four key locales, including the northern Chiricahua southern Dos Cabezas Mountains (Fig. 2...
