| 中文摘要: |
| 悉尼铜钼矿位于加拿大新斯科舍省阿巴拉契亚成矿带北东部,区内出露有元古宇Coxheath组玄武质、安山质、流纹质火山岩和中酸性侵入岩,在中酸性侵入岩内部查明有数十条铜金钼细脉状、网脉状矿(化)体,矿(化)体及成矿元素的分布、蚀变具有明显的斑岩矿化分布特征。多项地质、物探信息显示地表出露的中酸性岩体不是铜金钼矿(化)体的矿致母岩,仅是赋矿围岩,铜金钼矿(化)体是由深部隐伏岩体形成的,这一认识为该矿勘查工作和找矿的突破提供了新的找矿思路和基础。 |
| 英文摘要: |
| Sydney’s Cu-Mo deposit is located in northeastern of Appalachian metallogenic belt in Nova Scotia, Canada, have exposed and distributed a number of Proterozoic Coxheath-Group basaltic and andesitic volcanic rocks and acidic intrusive rocks, in which some veinlets and stocwork contained Cu-Mo, Cu-Au mine. Many acquired geological and geophysical datas show that the Cu-Mo, Cu-Au mine did not formed by the acidic intrusive exposed on ground and originated from deeper “concealed intrusive rock”, only, the acidic intrusive rocks exposed on ground are the country rock of Cu-Mo and Cu-Au mine, this new understanding and ideas will provide a chance of breakthrough of exploration. |
