And then the mode of occurrence of these elements and their potential washability in the process of coal preparation are discussed.

讨论了大同 1 0 - 1 1 #煤中 36种微量元素的含量分布，通过浮沉试验及煤岩组分定量统计，运用 Salori方法，计算了 1 4种有害微量元素在大同煤不同煤岩组分中的分布，进而分析了其赋存状态及其在煤炭洗选过程中的脱除潜力。

Taking Bendong and Xiqiu granitic bodies as an example, the thesis expounds geochemical characteristics of mantle-derived type granitoids in Sourthern China in REE and trace elements as follows: lower ∑REE, obvious fractionation of LREE and HREE, negative anomaly of Eu, relative higher ∑LREE/∑HREE,〓 and 〓 ratioes, rich in transitional elements and poor in large-ion lithophile and immobile elements compared with acidite means by Vinogradov. Original mantle-normalized distribution pattern of incompatible elements is one kind of rich -in-strongly incompatible elements type with enrich of K and loss of Sr, P, Ti and trace element association makes a feature of siderophile and chalcophile elements. The tectonomagmatic discriminating shows that mantle -derived granitoids in Southern China belong to orogenic granitoids formed in island arc/marginal sea basin system.

以本洞和西裘岩体为例，论文阐明了华南幔源型花岗岩稀土和微量元素地球化学特征，表现为稀土总量较低，轻重稀土元素分馏明显，负铕异常和∑LREE/∑HREE、〓、〓比值较高，与维氏酸性岩平均值相比华南幔源型花岗岩过渡族元素含量较高而大离子亲石元素和非活动性元素含量较低，不相容元素原始地幔标准化分配型式属强不相容元素富集型并呈K富集而Sr、P、Ti亏损的特点，微量元素组合以亲铁和亲铜元素为特征，构造岩浆判别显示华南幔源型花岗岩属造山花岗岩，其形成构造环境为岛弧/边缘海盆系统。
