布阿泽尔
Morocco
摩洛哥的布阿泽尔是全球首要的钴砷化物矿物产地,也是粉红色钴砷酸盐——玫瑰砷钴矿的原乡。
The Bou Azzer district, in the Anti-Atlas of Morocco, is a major 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.
