| Summary: | The Magma mine in the Pioneer (Superior) mining district, approx 70 miles E of Phoenix, Arizona, has been the source of many fine mineral specimens. The orebodies are mesothermal deposits of vein and limestone replacement types. The 'D' horizon of the Escabrosa and 'A' bed of the Martin limestones were among the most prolific specimen-producing sections. Some of the most notable occurrences include native copper crystals; fine crystals of chalcocite; pyrite in cubes, octahedra and pyritohedra; transparent, twinned calcite crystals; and extremely fine baryte crystals.
