| 摘 要： | 大庙子—菜抢子金矿区主要矿石类型有含金黄铁矿型和含金多金属型,对两类矿石研究表明金赋存于黄铁矿和交代、穿切黄铁矿的黄铜矿中,主要与黄铁矿有关。采用相关系数法、距离系数法及离差平方和法对38件矿石样品中的Au、Ag、Cu、Pb、Zn、Co、Ni、Bi元素进行R型聚类分群,结果为Au Bi、Ag Zn Cu Co Pb Ni二群。本矿区中金主要形成于金-黄铁矿阶段,少量形成于金-多金属阶段。 |

| Abstract: | The Damiaozi-Caiqiangzi minerogenetic region mainly contains two types of gold ore:the gold-pyrite and gold-polymetallic.Research on these two types ore shows that the gold exists in both the pyrite and chalcoyrite irruptiing or replacing the pyrite,but mainly in the pyrite.Applying correlated coefficient,distance coefficient and DEVSQ,trace elements Au,Ag,Cu,Pb,Zn,Co,Ni,Bi of 38 piece samples are analyzed by R-type clustering,the results show that the trace elements were separated into two groups:Au Bi,Ag Zn Cu Co Pb Ni.The gold in the present area mainly formed in the gold-pyrite stage,while little in the gold-polymetallic stage. |
