比斯比
Arizona, USA
位于美国亚利桑那州骡山的比斯比,是世界经典铜矿区之一,以浓艳的蓝铜矿与饱满的绿色孔雀石著称。
Bisbee, in the Mule Mountains of southern Arizona, is one of the most famous copper-mining districts in the world and a celebrated source of fine secondary copper minerals.
The Copper Queen and Lavender Pit
Bisbee's rich copper orebodies — worked from the 1880s through the Copper Queen mine and the great Lavender Pit — formed where copper sulfides oxidised near the surface, producing a spectacular suite of brightly coloured secondary minerals in the limestone host rock.
Signature minerals
Bisbee is best known for its intense blue azurite — 'Bisbee blue' is a benchmark for the species — together with green malachite, red cuprite and native copper. Fine azurite and azurite–malachite specimens from Bisbee are among the most prized of all American minerals.
