砷钇铜石(英语:Agardite)[1]是由砷钇铜石-(Y)[2],砷钇铜石-(Ce)[3],砷钇铜石-(Nd)、[4]和砷钇铜石-(La)组成的矿物组。[5],是含稀土元素(REE)和铜的水合砷酸盐,化学式为(REE,Ca)Cu6(AsO4)3(OH)6•3H2O,结构中亦含钇、铈、钕、镧以及微量其他稀土元素。砷钇铜石-(Y)分布最多,属六方晶系,呈针状黄绿色晶体。砷钇铜石矿物是砷铋铜石(mixite )结构族的一员,其化学通式为Cu2+6A(TO4)3(OH)6•3H2O,其中A为稀土元素、Al、Ca、Pb或Bi,T为P 或As。除了四种砷钇铜石矿物外,砷铋铜石(mixite)矿物组的其他成员是磷钙铜石(calcipotersite)[6],砷钇铝铜石(goudeyite),petersite-(Ce)[7], petersite-(Y)[8], plumboagardite[9] 和扎水羟砷铜石(zálesíite)[10]。
发现
砷钇铜石是在摩洛哥Djebel Sarhro的Bou Skour矿中被发现的第一个砷钇铜石族矿物。[11]。1969年Dietrich以法国地质学家Jules Agard的名字命名。[12]。
产地
已知产地包括德国[13], 捷克共和国[14], 希腊[15],意大利[16], 日本[17], 纳米比亚[18], 波兰[19], 西班牙[20], 瑞士[21],英国、[22] 和美国 [23]等地。
