名稱   綠銅鋅礦	Name   Aurichalcite
化學公式   (Zn,Cu)5(CO3)2(OH)6	Chemical Formula   (Zn,Cu)5(CO3)2(OH)6
莫氏硬度   1-2	Mohs scale of Hardness   1-2
描述   金剛砂石是銅和鋅礦床中的次要礦物，通常被發現為藍色或綠色的硬皮或微小針狀晶體的墊層，通常呈羽毛狀，簇狀，果皮狀。 很少發現為柱狀晶體聚集體或層狀聚集體的殼或顆粒聚集體。	Description   A secondary mineral in copper and zinc deposits, aurichalcite is typically found as blue or green crusts or mats of tiny acicular crystals, often as feathery, tufted, druzes; more rarely it is found as columnar crystal aggregates or crusts of either lamellar aggregates or as granular aggregates.
小挑戰   發源地 Aurichalcite來自許多經典的歐洲銅氧化礦床。 這些國家包括法國的切西； 希臘Laurium；蘇格蘭的利德希爾斯； 還有德比郡的Matlock和英格蘭坎布里亞郡的Caldbeck Fells。歐洲發生的其他事件包括意大利托斯卡納里窩那省的坎皮利亞馬里蒂瑪（Campilia Marittima；以及德國北萊茵-威斯特法倫州Wolfrath的Rohdenhaus採石場。	Challenge   Occurrence Aurichalcite comes from many of the classic European copper oxidation deposits. These include Chessy, France; Laurium, Greece; the Leadhills of Scotland; and Matlock, Derbyshire and Caldbeck Fells, Cumbria, England. Other European occurrences include Campiglia Marittima, Livorno Province, Tuscany, Italy; and the Rohdenhaus Quarry, Wolfrath, North Rhine-Westphalia, Germany.
