铜川矿区韩古庄-演池勘探区含煤岩系中镓分布特征
|
摘要
为了评价韩古庄-演池煤田勘探区含煤岩系中镓的资源潜力,统计了该勘探区的煤田地质资料与试验结果数据,对该勘探区石炭-二叠纪含煤岩系中镓的分布特征、影响因素及地质成因进行了分析。结果表明:该勘探区煤层、顶底板及夹矸中的镓富集明显,下部煤层及顶底板、夹矸中镓含量的加权平均值均超过了镓的边界品位,镓含量在垂向上随着煤层层位的降低而递增,且同一煤层底板中镓的含量较顶板和煤中高,平面上东部较西北部高。太原组底部的铝土质泥岩为镓的主要物质来源,石炭-二叠纪期间的成煤环境决定了镓的富集,构造运动为镓的富集创造了有利的沉积环境条件。
In order to evaluate the gallium resource potential in the coal-bearing rock series of Hanguzhuang-Yanchi Coalfield Exploration Area,the statistics were conducted on the coalfield geological information of the exploration area and the data of the experiment results.An analysis was conducted on the distribution features,influence factors and geologic genesis of the gallium in the Carboniferous-Permian coalbearing rock series of the study area.The results show that the gallium enrichs obviously in the seam,roof and floor as well as partings in the study area.The weighted average value of the gallium in the underneath seam as well as the roof and floor,and the partings all are over the marginal grade of the gallium. The gallium content in the vertical direction increases with the seam level decrease. In the same seam floor,the gallium content is higher than the roof and seam.In a plane direction,the gallium content in the east is higher than the northwest.The bauxite mudstone in the bottom of Taiyuan Formation is main material resources of the gallium.The coal-forming environment in the Carboniferous-Permian period made the enrichment of the gallium.The tectonic movement created the favorable sedimentary environment conditions of the gallium enrichment.
