The Mescal Limestone metamorphosed, forming asbestos and superheated diabase magma "baked" the limestone to marble. Most drinking water is drawn from surface water sources, including Bureau of Reclamation dams and the Central Arizona Project diversion. Invertebrate fossils are common in marine deposits from this period. Eventually, the ash and basalt that solidified inside the collapsed caldera uplifted and eroded. Bisbee, Arizona, 92 miles southeast of Tucson experienced secondary oxidation and enrichment to form high-quality malachite and azurite.
