Azurite with Malachite

specimen number:
2133252

location:
Bisbee, Cochise Co., Arizona, USA

description:
Neat geode like cavity lined with attractive crystallized azurite and green crystallized malachite. In great condition.

The Bisbee mining district, located in the Mule Mountains of Cochise County, Arizona, stands as one of the most prolific mineral localities in American history. Geologically, the area is defined by the Warren Mining District, where massive copper-sulfide replacement deposits formed within Paleozoic limestones, primarily the Martin and Escabrosa Formations, during the Jurassic-aged Sacramento Hill porphyry intrusion. These geological events produced not only vast amounts of copper ore but also world-famous secondary carbonate minerals, including breathtaking specimens of deep-blue azurite and vibrant green malachite. Historically, mining began in 1877 after the discovery of the Copper Queen claim, leading to nearly a century of intensive industrial activity led by companies like Phelps Dodge Corporation. The district transitioned from high-grade underground operations to massive open-pit mining at the Lavender Pit in the 1950s, until primary production finally ceased in 1975 due to depletion and falling metal prices. Today, Bisbee remains a legendary site for both its industrial heritage and its contribution of museum-quality mineral specimens to collections worldwide.
