关于此标本
尺寸: 3.8 × 3.3 × 3.3 cm (1.50 × 1.30 × 1.30 in) · 38 mm (1.50 in).
两枚蜜琥珀色的白钨矿晶体低伏于浅银绿色的白云母床上,晶面呈阶梯状且略带树脂光泽,光线穿过较厚的边缘时颜色转深为焦橙色。 下方的云母书层层交叠向外散开,冷调而无光,与温暖的晶体形成对比。 较大的那枚白钨矿展现出本矿种形成双晶时特有的扁平假八面体轮廓。
白钨矿是钨酸钙,化学式 CaWO4,为钨的两大主要矿石之一,就其体积而言拿在手上意外沉重——比重接近 6。 在短波紫外光下,它会回以强烈的蓝白色辉光,是矿物学中最可靠的萤光反应之一。 莫氏硬度 4.5 至 5,不需太大力气便会刮伤,而云母母岩更软。
尺寸精巧,3.8 × 3.3 × 3.3 cm、重 80 g,安坐于自身的云母基底上,不附底座。 此处拍摄的正是所售的这一件标本——绝无替换。
