比斯比
USA
位於美國亞利桑那州騾山的比斯比,是世界經典銅礦區之一,以濃豔的藍銅礦與飽滿的綠色孔雀石著稱。
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.
