摘要
对山东后大雪金矿床黄铁矿的成因矿物学研究 ,指出成矿早期黄铁矿富 As、Sb、Au,晶胞大 ,结晶度指数低 ,相对贫 Ti、Mn、Co、Ni,Ag,中期贫 As、Sb,富多金属 ,矿化与早、中期关系密切。据黄铁矿的热电性和微量元素判别指数 ,判断后大雪金矿床 3号脉剥蚀最浅 ,深部矿化较好 ,是本区找矿的重点 ,2号脉剥蚀较深 。
On the basis of study on minerageny of pyrite in Houdaxue gold ore deposit of shandong province,It has been pointed out that the pyrite in early stage of mineralization is not only rich in As,Sb and Au,but of large lattice cell,low crystallinity index and relatively poor in Ti,Mn,Co and Ni、Ag also. Gold mineralization is closely related with As,Sb and Au.It can be predicted that the No.3 vein of Houdaxue gold ore deposit has suffered little denudation and should be the key area of mining,No.2 rein has suffered relatively severe denudation and No.9 vein most severe one,considering the special index of pyroelectricity and trace elements.
