| 摘 要： | 金顶铅锌矿曾被认为是形成于相对被动地受构造与沉积相控制的盆地流体,类似于许多其他沉积岩容矿的金属矿床。然而,一些近期研究显示在金顶矿区露天采场存在砂岩灌入体、侵位角砾岩和水力压裂构造,说明矿床可能形成于超压流体的爆发性释放。文中报道在地下坑道（跑马坪和峰子山）中新观察到的与超压流体有关的构造,这些构造显示比露天采场有更...

| Abstract: | The Jinding Zn-Pb deposit has been generally considered to have formed from circulating basinal fluids in a relatively passive way,with fluid flow being controlled by structures and sedimentary facies,similar to many other sediments-hosted base metal deposits.However,several recent studies revealed the presence of sand injection structures,intrusive breccias,and hydraulic fractures in the open pit of the Jinding deposit and suggested that the deposit was formed from explosive release of overpressured fluids... |
