内蒙古安家营子金矿床地球化学异常特征
Characteristics of Geochemical Anomaly of Anjiayingzi Gold Deposit, Inner Mongolia
【摘要】 安家营子金矿床位于内蒙东部赤峰金矿成矿区,主要类型为破碎带交代蚀变岩型。矿脉呈对称蚀变分带。指示元素Ag、Cu、Pb、Zn、As、Bi、Mo、W、Ni和Co与成矿元素Au呈正相关。聚类分析和指示元素垂向分带序列计算结果与金矿床中的普遍规律不一致,似无规律可循。这很可能是一个好信息,说明下部矿体的地球化学晕对上部矿体的晕的叠加作用。
【Abstract】 he Anjiayingzi gold deposit is located on the south of Chifeng deep fault in EW direction and west of the Balihan deep fault in NNE direction It is a part of the Chifeng gold deposit Mesozoic granitoids are developed, and are closely with gold ore deposit at the times and the spaces Alterationmetasomatic type of gold deposit is the main one in the Anjiayingzi region Ore veins zoning symmetrically from outer to inner are: Afresh quartz monzonite(wall rock), Bchloritepyritization zone, Cpyritizationsericitiation zone, Dsilicification zone, and Eore body(mainly pyrites and quarts) They show the positive correlations between the indicator elements of Ag,Cu,Pb,Zn,As,Bi,Mo,W,Ni and Co and oreforming element of AuCluster analysis and calculations of vertical zoning for indicator elements are inconsistent with universal laws on gold ore deposits, and looks are not abide by laws, and showing disorderly and unsystematical It is possibly a good information which indicates geochemical anomalies of deep body are superimposed on one of shallow body
