Metallogenic mechanism and prospect of key metal beryllium Open
铍是战略性新兴产业和国防军工行业不可替代的一种关键金属,其赋存形式、成矿机制以及资源分布是关键金属矿产研究的重要内容。地球化学性质上,铍在大部分造岩矿物晶体结构中表现为不相容,倾向在岩浆演化晚期甚至热液阶段富集结晶。然而,铍又是一种典型的双性元素,在酸性和碱性环境中均可得到富集沉淀,因而铍矿主要赋存于花岗质岩石和碱性岩及其相关岩石中,与岩浆-热液过程相关的铍矿床主要包括"火山岩型"铍矿、高分异花岗岩-伟晶岩型铍矿、云英岩-石英岩型铍矿、碱性岩型铍矿、矽卡岩型铍矿、碳酸岩型铍…
