摘要
黄金坪金矿床以自然金(银金矿)—多金属硫化物—碲金银系列矿物—碲化物以及石英、黄铁矿等矿物组合为特征;典型元素组合为Au(Ag)-Te-Cu-Pb-Zn-Ba-As。本文应用数理统计方法研究Ⅰ号矿体的原生晕及其分带特征,结果表明侧向分带(矿体向围岩)趋势As-Zn-Pb-Au-Ag-Te-Cu-Ba,垂向分带(由上至下)为Pb-Ag-Au-Zn-As-Te-Cu-Ba。该分带模式对于深部矿化预测与其它矿化带的远景评价具有现实意义。
The mineral assemblage is characterized by natural gold (and electrum)—Cu, Pb, Zn sulfides-Te, Au, Ag mineral series-telluride-pyrite-quatz, at Huagjinping gold deposit. The typic element association appears as Au(Ag)-Te-Cu-Pb-Zn-Ba-As. It is important for us to study the zoning feature of the primary halo. The authors researched on the (?)chemical zoning pattern of orebody No. 1 with statistics. The result showes that horizonal zoning: As-Zn-Pb-Au-Ag-Te-Cu-Ba(orebody to wallrock) and vertical zoning (upper to lower): Pb-Ag-Au-Zn-As-Te-Cu-Ba. To forecast minera lization of the depth and to apprais long-range prospective of the other occurences with the zoning model of the primary halo have an actural significance.
