Basic Characteristic of Epidote from Shangluo, Shanxi Province

摘要: 陕西商洛产出的绿帘石,颜色主要为黄绿色、墨绿色或近于黑色;晶体以柱状为主,纵纹发育,半透明—透明;折射率为1.741~1.774,密度为3.34~3.49g/cm³。绿帘石的颜色与其w(FeO)有关。红外光谱中水的吸收明显;晶体中有大量的气-液两相包裹体和液相包裹体,裂隙发育。

Abstract: Epidote has the colours of yellowish-green,blackish-green or black,reflective index of 1.741~1.774,specific gravity of 3.34~3.49g/ cm³. Most of crystals are semi- transparent to transparent. Crystal of epidote is prismatic and longitudinal lines developed on crystal faces. Its colour is related to Fe content.Its infrared spectrum has absorption peak of water.Mean- while,there are many two- phase inclusions,liquid inclusions and cracks in crystals.
