| 摘 要： | 论述了贵州下石炭统祥摆组 (黔中九架炉组 )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 (Sc)矿床的形成条件。

| Abstract: | This paper deals with the geochemical characteristics of Sc in bauxite and its source and evolution, as well as the relation between Sc and REE in Lower Carboniferous bauxite. The REE distribution patterns and some parameters of bauxite are similar to those of Sinian clay rocks and dolomites. It is indicated that Sc and REE seem to have come from the Sinian clay rocks and dolomites. Based on the sulfur isotopic composition and Eh\|pH diagram this paper discusses the metallogenetic conditions of bauxite (Sc) deposits. |
