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 .3 4～ 3 .49g/cm3 。绿帘石的颜色与其 w( Fe O)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。
Epidote has the colours of yellowish- green,blackish- green or black,reflective index of1 .741～ 1 .774,specific gravity of3.34～ 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.
