“碳”,包括石墨、非晶质碳和各种碳质物是各种类型金矿床中的常见矿物。金矿床的黑色、灰色石英和碳酸盐中常含有石墨和非晶质碳,金矿床的裂缝中、滑动面上、角砾岩化部分以及沿断层面的不规则块体中也常常发现碳质矿物。碳还富集在自然金和其他金矿物中。在很多金矿体中,经常发现附着在滑动面上的自然金。金的富矿体常常产在矿脉与石墨层的交切部位,西方老矿工们把这种碳质层称之为“黑色引导”(black leader)或“标志”(indicators)。
“Carbon,” including graphite, amorphous carbon, and various carbonaceous materials are common minerals in various types of gold deposits. The gold, gray quartz and carbonate often contain graphite and amorphous carbon in the gold deposits, and the carbonaceous material is often found in the fractures, sliding surfaces, brecciated parts of the gold deposits and irregular blocks along the fault plane mineral. Carbon is also enriched in natural gold and other gold minerals. In many gold bodies, the natural gold attached to the sliding surface is often found. Gold-rich ore bodies are often found at the intersections of veins and graphite layers, and the old Western miners call the carbonaceous layer “black leader” or “indicator.”
