布阿澤爾
Morocco
摩洛哥的布阿澤爾是全球首要的鈷砷化物礦物產地,也是粉紅色鈷砷酸鹽——玫瑰砷鈷礦的原鄉。
The Bou Azzer district, in the Anti-Atlas of Morocco, is the world's premier source of cobalt minerals — famous for rose-pink roselite and crimson erythrite.
A cobalt-arsenide district
Bou Azzer is mined for cobalt, nickel and arsenic, and its oxidised zones produce some of the finest cobalt-arsenate minerals known. It is one of very few places mined primarily for cobalt rather than as a by-product.
Signature minerals
The signature species are crimson erythrite (cobalt bloom) and rose-to-magenta roselite, alongside skutterudite, and occasional native silver and gold. Saturated pink and red cobalt minerals on matrix are the prize.
