摘要
从矿石学、矿物学和矿物地球化学的某些角度出发,研究和总结了黔东内生金矿的综合找矿标志。结果表明具有条带状、角砾状、块状和呈灰色、烟灰色、浅灰色、韧性强的矿石具有较高的金品位;矿物粒度细小、种类多、组合复杂、石英具强油脂光泽等表明它们具有金的高含量且与自然金共生;大量液体CO2包裹体的出现及CO2的高含量,预示金的高度富集;较高的温度与较强的围岩蚀变有关,也是金矿化的良好标志。
Based on the study of ore mineralogy and mineral geochemistry of endogenetic gold deposits in Eastern Guizhou, their main ore-hunting indicators have been summarized.The study shows that the ores that display banded, brecciform and massive textures and high tenacity and are coloured in grey, ash grey and light grey have higher grade of gold; the ores that contain various types of finer grain size quartz and sulfide minerals, complex mineral association and quartz with strong oily luster have high gold content and are generally associated with natural gold; in addition, the presence of a large amount of CO2 liquid inclusions and the occurrence of high CO2 values indicate highly concentration of gold; also, strong wall-rock alterations related to higher mineralized temperature are a good ore-hunting indicator for gold deposits
