·绿帘石柱状晶体

绿帘石是一种羟基硅酸盐矿物,产于变质岩中。单斜晶系,晶体呈柱状、棒状,晶面有纵晶纹,集合体呈粒状。透明至半透明,玻璃至油脂光泽。颜色主要有黄色、黄绿色、绿色、褐绿色、棕褐色、褐色和黑色。绿帘石多色性很强,同一晶体的三个方向,可见绿色、褐色、黄色三种颜色。透明晶体可磨制成刻面宝石,十分漂亮。

宝石级晶体主要来自奥地利,大多为褐色。黄色晶体产自美国阿拉斯加,黄绿色晶体大多产自巴西,其他产地还有意大利、挪威等。宝石有用于首饰,通常作为收藏。

Epidote is a calcium aluminum iron silicate hydroxide that forms columnar or tabular crystals with striations parallel to the crystal’s length. It is mostly green to dark green in appearance and is easily recognizable by its strong pleochroism, with the same stone appearing green, brown or yellow depending on the direction from which it is viewed. Epidote occurs widely in low-grade regionally metamorphosed rocks and is a common rock-forming mineral.
