| 摘 要： | 通过对29个钻孔的200件煤样锗含量分析，发现20个钻孔锗含量沿煤层纵向有6种变化形式。特别值得注意的是，大多数钻孔显示锗含量在煤层中部出现高峰值，而有别于以往所报道的锗只在煤层项、底部相对富集的研究结论。笔者认为，胜利煤田锗的富集主要发生在泥炭化阶段，主要作用机制是有机质的吸附作用；此外，锗的聚集强度还随着原始沉积环境和锗源供给条件而变化。 |

| Abstract: | The paragenetic germanium deposit of coal in Shengli Coalfield was discovered in recent years and provided with autocephaly exploitation value in China.Through the analysis of 200 coal samples from 29 boreholes 6 variation patterns of germanium grade within coal-seams along uprightness have been discovered.Especially,germanium grade appeared pinnacle value in the middle of the coal-seams of majority bores in Shengli Coalfield.It is different with many research conclusion reported previously that pinnacle value of germanium grade only located in the top and bottom of coal-seams.Therefore,the author thinks that accumulating of germanium mostly took place in the peat formation stages,mostly process mechanism is sorption by organic matter from peripheral circulating solution,germanium enrichment intensity changed with original sedimentary environments and providing conditions of germanium. |
