| Description/Abstract | Majuba Hill is a complex plug of rhyolitic rocks of Tentiary (?) age in the central part of the Antelope Range, Pershing County, Nev. The plug intrudes sedimentary rocks of Triassic(?) age, which consist chiefly of argillite with smaller amounts of quartzite and impure limestone. It is about 5,000 feet in diameter and has apophyses that extend beyond its margin. The rhyolitic rocks are of three varieties that are here called earlier rhyolite, rhyolite porphyry, and later rhyolite. Five main varieties of intrusive breccia occur in dikes and irregular masses cuting the older rhyolitic rocks. The rhyolitic rocks of the plug and the intruded sedimentary rocks have been silicified, sericitized, and tourmalinized. Three principal preore faults are exposed in the Majuba Hill mine. The largest of these, the Majuba fault, strikes N. 30 W., dips 54 -84 SW., and has a displacement of about 155 ft. Copper and tin are the principal ore metals at Majuba Hill. From 1916 to 1949 slightly more than 27,000 tons of copper ore was produced from the Majuba Hill mine. About 350 tons of tin ore also has been shipped from this mine and small quantities of lead-silver and arsenicsilver ore have been produced from properties nearby. Uranium is locally associated with the copper and tin deposits in the Majuba Hill mine but has not been mined. (auth) |
