摘要
山东省五莲县七宝山隐爆角砾岩呈北西向拉长的椭圆形.石英闪长玢岩向上和外围分枝,向下逐渐汇合成筒状.金铜矿体受矿化角砾岩筒控制,亦呈筒状.
The Qibacshan hidden explosive breccia pipe described in this paper is located in Wulianc oounty,Shandong and has a cylindrical shape with an elliptical cross-section (its major axis stretchingalong northwest direction and its cross-sectional area progressively becoming small from the top to thebottom). The whole intrusive is composed of quartz diorite porphyrite. The Au-Cu-bearing ore bodywas contilled by the mineralized breccia pipe during its emplacement. So it has a pipe-like shape.
