Geological Background
Turquoise is a secondary mineral formed by the chemical reaction of copper-rich water percolating through porous rocks containing aluminum and phosphorus minerals. It typically forms in arid regions where groundwater interacts with copper deposits, such as in desert climates.
The Kingman turquoise mine is located in northwestern Arizona, USA, near the city of Kingman. The geological setting of the mine is within the mineral-rich region of the Cerbat Mountains. Turquoise deposits in this area are associated with volcanic activity that occurred millions of years ago.
The turquoise deposits in the Kingman mine primarily occur in veins and nodules within the host rock, which is typically a type of altered and fractured rhyolite or volcanic rock. These veins and nodules contain the turquoise mineral along with other associated minerals, such as chalcosiderite, quartz, and pyrite.
The formation of turquoise in the Kingman mine likely occurred over millions of years through a process involving the percolation of copper-rich water through fractures and cavities in the host rock. As the water interacted with aluminum and phosphorus minerals present in the rock, it led to the formation of turquoise.
The geological history of the Kingman turquoise mine, with its unique combination of volcanic activity, mineral-rich rocks, and hydrothermal processes, has contributed to the formation of high-quality turquoise deposits that have been mined and prized for centuries.
