锌自然铜发现于广西大厂矿田中,其产状有二,一是产于X号剖面723孔的矽卡岩岩心样品中,共生矿物有符山石、钙铝榴石、斧石和少量黄铁矿、毒砂和黄铜矿等。二是产于铜坑地区石炭纪灰岩中的针铁矿铁帽中,共生矿物主要是针铁矿,其次是石英和少量自然银。 双目镜下观察,矿物呈树枝状或薄片状,颗粒一般大小是:长×宽=0.28×0.08毫米,最大0.49×0.11毫米。金黄色,比黄金的颜色稍浅。强金属光泽。富延展性。维氏硬度121公斤/毫米~2,相当摩氏硬度3.3。计算比重为8.44。反光镜下观察,比黄金的颜
Zinc Natural Copper was found in Dachang orefield in Guangxi Province. The occurrence of Zinc spontaneous copper was found in the samples of skarn core 723 in section X. The symbiotic minerals include Fu Shan, Garnet, Axolith and a small amount of pyrite , Arsenopyrite and chalcopyrite. Second is produced in the copper pit calcite limestone in goethite iron cap, the symbiotic mineral is goethite, followed by quartz and a small amount of natural silver. Binocular observation, the mineral was dendritic or flaky, particle size is: length × width = 0.28 × 0.08 mm, the largest 0.49 × 0.11 mm. Gold, slightly lighter than the color of gold. Strong metallic luster. Rich ductility. Vickers hardness of 121 kg / mm ~ 2, a considerable Mohs hardness of 3.3. The calculated weight is 8.44. Reflective observation, more than the color of gold
