| [摘要]野狼沟锌多金属矿(床)点是通过1颐150000 水系沉积物测量,在对分散流异常查证时发现
的。该点有较发育的具褐铁矿化的构造蚀变带,挤压的片理化和岩石破碎明显,具有As、Zn、W、Mo、Sb、
Bi、Ag 等元素的水系沉积物组合异常,异常峰值明显,连续性较好。其中发现有挤压透镜体,其核心发
现有原生金属硫化物残留体。岩石地球化学异常在铁帽部位有明显的Zn、Ag、As、Sb、Sn、W、Mo 等元素
的异常反映,峰值明显,强度极高。通过地表槽探工程揭露和化学样采集,并在地表探槽工程中系统采
集岩石地球化学样品,以圈定矿体地表原生晕,最终肯定了野狼沟锌多金属矿的远景。 |

| Abstract:The Yelanggou Zinc Poly-metallic deposit was discovered by means of 1:50000 stream sediment survey and identification of geochemical a鄄
nomalies. There exists a structural alteration zone with limonite, which is obviously characteristics of squeeze of slice and broken rocks, above which lie
mixed elements anomalies of As, Zn, W, Mo, Sb, Bi, and Ag, which have remarkable peaks and good continuity. There are squeezed lentoid bodies in
the structural alteration zone, where relicts of metal sulphide are found at the central portion. Field tests have enabled identification of distinct multi-ele鄄
ment lithogeochemical anomalies of Zn, Ag, As, Sb, Sn, W, and Mo. in the gossan zone, which have high peak values and large intensity. By means
of trench exploration and collection of chemical samples, the primary haloes of the orebody on the surface are delineated. Finally, the prospect of the Ye鄄
langgou zinc poly-metallic deposit is confirmed. |
