| 摘 要： | 利用综合物化探方法开展多金属找矿,在二道河地区首次发现了银多金属矿.矿体主要赋存于奥陶纪裸河组含泥质白云质灰岩、变质细砂岩和侏罗纪满克头鄂博组火山碎屑岩中,严格受北东向构造带控制,断裂呈平行雁列式排列,异常总体呈宽带状沿北东向和北西向断裂呈"V"字形展布,由Ag、Pb、Zn元素组成,伴有Cu、Au、W、Mo、Sn、Bi、As、Sb等元素,异常套合十分紧密、强度高、规模大、浓集中心明显.二道河银多金属矿的发现对在该区进一步找矿具有重要意义.

| Abstract: | An Ag-polymetallic deposit was found at Erdaohe area using the comprehensive geophysical and geochemical methods.The ore bodies are in the dolomitic limestone,metamorphic fine sandstone of Luohe group of Ordovician system and Manketouebo group of Jurassic system.They are controlled by the NE parallel echelon tectonic faults.The anomaly consisting mainly of Ag,Pb and Zn shows V type tracing NE and NW faults,and contains Cu,Au,W,Mo,Sn,Bi,As and Sb.All anomalies have high intensity,large scale and good concentration centers.The finding of Erdaohe Ag-polymetallic deposit is important for further exploration in this region. |
