【摘要】 辉锑矿脉为沃溪钨锑金矿床最具工业价值的矿石类型。本文报道了近期对该型矿石的主要矿石矿物如自然金、自然锑、辉锑矿、白钨矿、黑钨矿等的观察研究和电子探针分析结果。分析了矿石矿物微量化学成分特征及其所揭示的矿床成因信息。研究表明 ,矿床成矿应与区域构造 岩浆作用有成因联系。从而建立了该矿床新的成矿机理模式。更多还原

【Abstract】 The stibnite ore vein is one of the major types of economic ores explo ited throughout the Woxi mining district in western Hunan, China. The current co ntribution reports the results of recent microscope observation and microprobe a nalysis for major ore minerals including native gold, native antimony, stibnite, scheelite, wolframite, etc. Also, the authors deal with the genesis of the ore deposit in terms of the trace chemical composition of major ore minerals from th e deposit. The results show that W Sb Au mineralization at Woxi might have a c lose genetic relation to the regional tectono magamtism developed during the g eological processes. Based on the data from this study and previous isotopic dat ing of ore mineralization in the deposit and of regional magmatic rocks/dykes, a new model has been put forward for the genesis of the deposit.更多还原
