阳储岭斑岩钨钼矿床白钨矿特征及形成条件的研究 总被引:2,自引:0,他引:2
白钨矿是主要的钨矿物之一。目前,国外对白钨矿的研究较详细,报道材料较多,除了研究天然的白钨矿-钼钙矿系列以外,还进行白钨矿-钼钙矿系列的合成实验研究。本文主要讨论阳储岭斑岩钨钼矿床白钨矿特征及形成条件。 一、白钨矿的矿化特征 相似文献

Geochemical characteristics of scandium are described with respect to its source,evolution and correlation with REE as observed in Late Sinian and Early Cambrian phosphorites and tuffs in Guizhou.Gomparison of chondrite-nomalized REE patterns and some other parameters between the phosphorite and tuff shows that scandium and REE are most likely to have been derived from earlier or contemporaneous marine volcanics or tuffs,with no indication of genetic link to the purple shales,silstones and dolomites in the area.The conditions under which the Sc-bearin phosphorites were formed are discussed in the light of sulfur isotopes and Eh-Ph constrains. 相似文献

铝土矿钪的地球化学特征 总被引:4,自引:0,他引:4
论述了贵州下石炭统祥摆组铝土矿钪来源与演化,钪地球化学特征和钪与稀土元素的相关性。铝土矿的稀土模式及某些参数与震旦系南沱组粘土岩和陡山沱组白云岩具有一致性表明,铝土矿的钪与稀土元素可能来自早期的粘土岩和碳酸盐岩类。最后,根据硫同位素组成和Eh-Ph图解,讨论了铝土矿矿床的形成条件。 相似文献
