| 摘 要： | 秦岭东段主要原生金红石矿床均受不同程度的变质作用形成。通过对该区四种主要金红石矿床稀土元素地球化学特征的分析及对含矿原岩的恢复，认为本区不同类型金红石矿床的∑ＲＥＥ、ＬＲＥＥ／ＨＲＥＥ、δＥｕ值等特征有很大差别，并显示出了本区金红石矿床成因的多样性和复杂性；稀土元素与Ｔｉ的富集关系的研究结果表明：任何一种类型矿床中，稀土越富集，轻、重稀土分异程度越高，δＥｕ值越大，越有利于Ｔｉ的富集。

| Abstract: | The Garboniferous Permian sequences in west Shandong have tremendous possibility of trapping coal gas,with the Shanxi and Taiyuan formations serving as principal gas sources.In some localitites,coalification once reached its peak twice,creating gas accumulating environments in no way inferior to those of known gas fields under operation and bringing a promising prospects to future coal gas exploration.According to stock assessment, Yanggu Renping and Caoxian Chengwu areas should be given first priority of being prospectingly drilled due to their high gas potentials. |
