{"title":"Older Precambrian rocks near the Salt River Canyon central Gila County, Arizona","authors":"D. Livingston","doi":"10.56577/ffc-13.55","DOIUrl":"https://doi.org/10.56577/ffc-13.55","url":null,"abstract":"INTRODUCTION Older Precambrian rocks are exposed along the Salt River from just upstream of Canyon Creek to below Horseshoe Bend. The river bed is cut in granitic, volcanic, and contact-metamorphosed sedimentary rocks. In many places the contact relations are obscured by a cover of Tertiary(?) volcanic and sedimentary rocks. Most of the Precambrian exposures are southeast of the river, in and near the area known as the Bronco Ledges ( Darton, 1925, p. 228-230.). Regional strikes and trends of contacts are northeast, parallel to the river, and dips are southeast. Strikes and dips can easily be measured on vitrophyre shards in the volcanic rocks, and on bedding in the orthoquartzites and shales. Sedimentary structures show that the southeast-dipping beds are not overturned. The oldest rock unit is a volcanic porphyry upon which were deposited orthoquartzites and then shales. This section was then intruded by the Ruin granite, and the whole group of rocks was eroded to a relatively smooth surface before the deposition of the younger Precambrian Apache group. VOLCANIC ROCKS The oldest formation so far observed is an acidic, porphyritic plagioclase vitrophyre. Subparallel, dark vitrophyric shards form an eutaxitic texture, indicating that the rock is an ignimbrite of probable explosive origin. In four localities, strikes of 28°, 72°, 52° and 67° azimuth were measured on the shards with southeast dips of 30°, 45°, 61° and 31°, respectively. The thickness of exposed outcrop indicates that this formation is more than 3,000 feet thick. This wide exposure is cut by at least one fault of unknown displacement, but the attitude of the fault is such that it crosscuts the exposure and would not tend to repeat stratigraphic sections. In thin section, the rock is porphyritic, with quartz, potassium-feldspar, and plagioclase (An.,„ An,„) crystals in a devitrified groundmass. Minor amounts of amphibole and biotite are present . The plagioclase phenocrysts are partially sericitized, and the biotite is strongly chloritized. Opaque minerals, where present, are magnetite. Two samples were run on an X-ray diffractometer and the major mineral phases indicated are quartz, plagioclase (An„ An,„) and biotite. SEDIMENTARY ROCKS An orthoquartzite is in depositional contact upon the older ignimbrite. The contact is subparallel with the eutaxitic banding and strikes northeast. No conglomerate or residual material has been observed at the contact. Shale beds are intercalated with the quartzite, and become more abundant in the upper portions of the sedimentary section. Cross bedding and oscillation ripple marks up to one foot in wave length are well developed, and leave no doubt that the beds are not overturned. These rocks have not been closely investigated at present, but appear to measure several thousand feet in thickness. Along the southeast they are bounded by their contact with the intrusive Ruin granite.
