含铜钨酸钙矿物系一稀少而较少之矿物,系一九四九年秋作者往铜陵鸡冠山区调查铜矿时首先发见者。该矿物色呈橄榄绿,硬度四与五之间,玻璃质光泽甚强。比重四·八至五,体为半透明,折光率一·八以上,为一正方系中正光性符号之单轴晶体矿物。该矿物生於石英脉之晶硐内,孔隙中或裂缝里,呈大小不一之不规则粒状或块状矿物;但含此矿物之石英脉则穿插于含铜Skarn之节理成裂缝内。共生矿物按其发生次第有石英,白钨矿,矽孔雀石,孔雀石,含铜钨酸钙,褐铁矿及高岭土等。该含铜钨酸钙石英脉位铜矿氧化带之Skarn范围内,且常与白钨矿共生。关系密切,为一次生作用造成之矿物。
The copper-containing tungstate mineral is a rare but lesser mineral, first observed by the author in his investigation into the copper mine in Jiguanshan district, Tongling in the autumn of 1949. The mineral color is olive green, hardness between four and five, very strong vitreous luster. The proportion of four to eight to five, the body is translucent, the refractive index of more than eighty, is a square system of positive phototropism of uniaxial crystal minerals. The mineral was born in the quartz vein of the crystal cave, pores or cracks, irregularly shaped or massive minerals, but the quartz vein with this mineral is interspersed with cracks in the joints containing copper Skarn. Symbiotic minerals according to their occurrence, quartz, scheelite, malachite, malachite, copper-containing calcium tungstate, limonite and kaolin and so on. The copper-containing calcium tungstate quartz vein copper oxide zone within the Skarn range, and often coexist with scheelite. Closely related to the minerals caused by a secondary role.
