摘要: 为了了解贵州西部产煤区煤矸石中微量元素的成矿潜力,选取黔西南、六盘水市、毕节等代表性的煤矿区为研究对象,采用GGX-600原子吸收分光光度计S-217和等离子质谱仪ICAPQS-319对矸石中具有成矿潜力的元素进行了测试。结果表明:在大多数矿区,煤矸石中Ga、Li、RexOy的质量分数达到了其边界品位或工业品位|康滇古陆为晚二叠世聚煤期唯一的陆源供给区,煤矸石中元素的富集应受到了陆源碎屑物质供给的影响|大面积沉降到成煤沼泽中的火山灰可能会造成煤矸石中元素的富集|断裂控制区内的兴义煤田和织纳煤田,是低温热液活动的分布区,煤矸石中元素的富集同样可能受到低温热液作用的影响。

Abstract: southwestern Guizhou, Liupanshui, Bijie, the important coal production regions in Guizhou are selected as our research target regions. Trace elements were analyzed by using GGX-600 and ICAPQS-319. The results showed that: the concentration rates of Ga, Li, RexOy in the gangue have reached cut-off industrial grade; The Kang dian ancient land is the only terrigenous detrial material’s supply area in the late Permian, the concentration of trace elements in the gangue should be affected by the terrigenous detrital materials supply; volcanic ash deposition could be the reason of trace elements enrichment in the gangue; The Xingyi coalfield and Zhina coalfield in the area by Fractures control, is the area influenced by low temperature hydrothermal process, epigenetic hydrothermal fluids intrusion could be responsible for the abnormally enrichment of trace elements in the gangue.
