Epidote·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。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。宝石级晶体主要来自奥地利,大多为褐色。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.·绿帘石棒状晶体·绿帘石中的气液内含物......
