| 摘 要： | 三个黄牛花岗岩型钨锡矿床与栗木复式岩体的第二阶段花岗岩有关,研究表明,三个黄牛隐伏花岗岩属超酸性过铝富碱一类岩石。矿体赋存于隐伏岩体浅部。矿石矿物黑钨矿、白钨矿、锡石主要以浸染状、细脉状及团块状产出,与钨锡成矿有关的交代作用有钠长石化、云英岩化以及晚期中低温热液蚀变作用,显示钨锡具有多阶段成矿,矿化延续时间长的特点。研究指出,在隐伏岩体岩沟凹陷内相对突起的部位继续寻找花岗岩型钨锡矿床具有一定的前景。

| Abstract: | The Sangehuangniu granite type tungsten and tin ore deposit is associated with the second phase granite of Limu composite massif.The research shows that Sangehuangniu concealed granite belongs to super acidic peraluminous alkali rich rock.The ore body occurs on the shallow part of the concealed rock.The ore minerals including wolframite,scheelite and cassiterite occur mainly as dissemination form,thin veins and massive form,the metasomatism associated with tungsten and tin mineralization is albitization,greisenization and epithermal to mesothermal hydrothermal alteration showing the characteristics of multiphase mineralization of tungsten and tin and long duration of mineralization.The research shows that there is certain prospective for further search of granite type tungsten and tin deposit in the relatively protrusive part in the depression of gryke of the concealed rock. |
