| 摘 要： | 叶家庄铜多金属矿区的矿体受阳新岩体石英正长闪长岩与碳酸盐岩围岩接触带控制,主要赋存于接触带矽卡岩和近接触带蚀变岩体中。矿床与燕山期石英正长闪长岩浆活动有紧密成因联系。石英正长闪长岩与碳酸盐岩接触带是寻找铜多金属矿的有利部位,矽卡岩化和硅化是重要的找矿标志。通过类比周边矿床认为,叶家庄矿区北西向接触带及深部有扩大矿床规模的潜力,同时具有向深部探索斑岩型铜矿的可能性。

| Abstract: | The ore body in the Yejiazhuang copper-polymetallic mining area is controlled by the contact zone between the carbonate rock and the Yangxin rock body,which mainly occurs in the contact zone skarn and near-contact zone altered rock body.It is believed that the deposits are related to the Yanshanian quartz syenite diorite magmatism.The contact zone between the quartz syenite and carbonate rocks is an advantageous location for searching for copper polymetallic deposits.Skarnization and silicification are important signs for prospecting.The article believes that the copper polymetallic ore body found in the Yejiazhuang mining area still has the potential of further expansion,and it also has the possibility to explore porphyry copper deposits. |
