摘要
研究表明:新城金矿床已发现工业矿体2条,均位于焦家断裂带下盘,呈似层状、层状产出;矿体从上至下具有"低品位→高品位→低品位"的变化规律;矿床围岩蚀变发育,下盘蚀变具有"黄铁绢英岩化碎裂岩带→黄铁绢英岩化花岗闪长质碎裂岩带→绢英岩化花岗闪长岩带→花岗闪长岩带"的变化规律;新城金矿床在深部以及倾向延伸方向具有较大的找矿潜力。
The research shows that:2 industrial ore bodies have been found in the new city gold deposits,all located in the lower plate of the jiaojia fault zone,with similar layer-like and layer-like output;The orebody from top to bottom has the change rule of "low grade→high grade→low grade";The wall rock alteration of the ore deposit is developed,and the footwall alteration has a change rule of "yellow iron sericizedcataclastic rock belt→yellow ironsericized granite diorite belt→sericized granite diorite belt".Xincheng gold deposit has great prospecting potential in the depth and trend extension direction.
