| 摘 要： | 对煤中金的国内外研究现状进行了综述，详细讨论了煤中金的分布规律、赋存状态与富集成因。世界范围内绝大多数煤中金的丰度较低，只有局部煤中金的含量异常，特别是在周围有金矿点或富金岩层的煤层中才有富金可能。含有较多金矿点的黔西南区煤中金的平均含量要明显高于黔北煤，具有成矿潜力。低温热液成因的硫化物（主要是黄铁矿）、石英和方解石脉可能是金的主要载体，腐植酸与黏土矿物的吸附也是煤中金的重要赋存方式。对任一金矿床来说，可能由多种地质因素引起金的富集沉淀，其中有机质、低温热液作用、纳米金的气相迁移以及矿物表面特性可能是煤中金富集的主要因素。

| Abstract: | Current studies on gold in coal in world were introduced,and the distribution,occurrence and accumulation causes of gold in coal were discussed in detail. Gold has a lower abundance in most coals throughout the world. However,anomalous gold content was found in some coals,particularly in the coal seams framed by gold mines or Au-specialized rocks and these seams were regarded as the most promising for gold accumulation. Gold has an obviously higher content in coals from Southwestern Guizhou Province contain... |
