砷釔銅石(英語:Agardite[1]是由砷釔銅石-(Y)[2],砷釔銅石-(Ce)[3],砷釔銅石-(Nd)、[4]和砷釔銅石-(La)組成的礦物組。[5],是含稀土元素(REE)和銅的水合砷酸鹽,化學式為(REE,Ca)Cu6(AsO4)3(OH)6•3H2O,結構中亦含釔、鈰、釹、鑭以及微量其他稀土元素。砷釔銅石-(Y)分佈最多,屬六方晶系,呈針狀黃綠色晶體。砷釔銅石礦物是砷鉍銅石(mixite )結構族的一員,其化學通式為Cu2+6A(TO4)3(OH)6•3H2O,其中A為稀土元素、Al、Ca、Pb或Bi,T為P 或As。除了四種砷釔銅石礦物外,砷鉍銅石(mixite)礦物組的其他成員是磷鈣銅石(calcipotersite)[6],砷釔鋁銅石(goudeyite),petersite-(Ce)[7], petersite-(Y)[8], plumboagardite[9] 和扎水羥砷銅石(zálesíite)[10]

發現[編輯]

砷釔銅石是在摩洛哥Djebel Sarhro的Bou Skour礦中被發現的第一個砷釔銅石族礦物。[11]。1969年Dietrich以法國地質學家Jules Agard的名字命名。[12]

產地[編輯]

已知產地包括德國[13], 捷克共和國[14], 希臘[15],意大利[16], 日本[17], 納米比亞[18], 波蘭[19], 西班牙[20], 瑞士[21],英國、[22] 和美國 [23]等地。
