为了研究比利时铅锌矿脉中伴生的硫铁化物的特征,探讨痕量元素是否能帮助搞清成矿条件,便于探寻隐伏矿体,用DC电弧光谱和X荧光光谱法对黄铁矿和白铁矿中的Tl、Ni、Co、Mn、Zn、Pb、Ge、Cd和As进行了系统分析.结果发现Tl含量(30～6800ppm)比所有其他矿床(Tl 10ppm)都高;Co Ni比值??1,比沉积矿都低. 硫铁化物中Tl的赋存状态不是以痕量矿物产出,就 In order to study the characteristics of pyrites associated with lead-zinc veins in Belgium and to explore whether trace elements can help to clarify the ore-forming conditions and facilitate the exploration of concealed ore bodies, the pyrite and white irons were characterized by DC arc spectroscopy and X-ray fluorescence spectrometry The systematic analysis of Tl, Ni, Co, Mn, Zn, Pb, Ge, Cd and As in the ore revealed that Tl content (30-6800 ppm) is higher than that of all other deposits (Tl 10 ppm) 1, which is lower than that of the sedimentary ore.The occurrence state of Tl in the ferrosilicon is not produced by trace minerals
