| 中文摘要:运用电离耦合等离子体质谱、X射线荧光光谱、带能谱仪的扫描电镜和逐级化学提取等技术,对贵州西部晴隆矿区晚二叠世K6煤层的元素地球化学特征进行了研究。研究表明,除Cu、S和Fe以外,斑铜矿是造成该煤层中Bi和Pb富集的主要原因。由火山灰、陆源碎屑和有机质组成的特殊“集合体”是引起该煤层中Cr、Cu、F、U和Zr异常的主要因素。 |

| Abstract:Geochemical characteristics of the Late Permian K6 Coal seam in the Qinglong Mine of western Guizhou Province were studied by such methods as inductively-coupled plasma-mass spectroscopy, X-ray fluorescence spectrometry, scanning electron microscopy equipped with energy-dispersive X-ray, and sequential chemical extraction. The results reveal that, in addition to Cu, S, and Fe, bornite is the main carrier of Bi and Pb. The high content of Cr, Cu, F, U, and Zr is attributed to the special material of volcanic origin. |
