河南小秦岭金矿为石英脉型金矿床,成因类型为岩浆期后热液型。矿石中主要矿物为石英,其次为金属硫化物;金矿物主要为自然金,其次为银金矿和含银自然金、碲金矿,碲金银矿微量。自然金为包体金和裂隙金及粒间金,粒度以中细粒为主,其成色普遍偏高。黄铁矿以中细粒半自形五角十二面体及其聚形含金最高。其中元素含量统计特征规律不明显。热电系数具明显指示作用。石英的晶体特征、元素含量具指示意义。其热发光,红外光谱为矿床评价重要标志。
The Xiaoqinling gold deposit in Henan Province is a quartz vein type gold deposit and its genetic type is hydrothermal type after the magmatic period. The main minerals in the ore are quartz, followed by metal sulfides; gold minerals are mainly natural gold, followed by silver and gold and silver-containing natural gold, tellurium gold, tellurium gold and silver trace. Natural gold for the gold and gold in the fracturing and intergranular gold, particle size mainly in the fine, its color is generally high. Pyrite to medium fine semi-self pentagonal dodecahedron and poly gold highest. Among them, the law of element content is not obvious. The thermoelectric coefficient has a clear indication. Quartz crystal features, elemental content indicates the meaning. Its thermal luminescence, infrared spectroscopy is an important symbol of deposit evaluation.
