| 拨茅山-牛头山铜矿床的的赋矿岩石为中生代的火成岩系。侵入岩-潜火山岩-火山岩构成完整的侵入-喷发系列。该矿床可分为火山气液-沉积铜矿床和斑岩型铜矿床两种类型。在成矿前期,陆相火山岩在湖底发生火山喷气、火山热泉以及火山热水沉积。潜火山岩的侵入,伴有长期热液循环活动,在张性断裂为主的赋矿空间生成与斑岩有关的各类型矿床。 |

| Abstract: |
| The Bamaoshan and Niutoushan copper deposits in Zongyang, Anhui are hosted in the Mesozoic igneous rock series, which are built up of a complete sequence of intrusive rocks, subvolcanic rocks and volcanic rocks. The copper deposits may be grouped into two types:the volcanic-exhalative-sedimentary copper deposit and porphyry copper deposit. The volcanic-exhalative, hot spring and volcanic hydrothermal sediments were accumulated at the bottom of lakes during the early mineralization. The intrusion of subvolcanic rocks and long-term hydrothermal activity led to formation of the porphyry-related copper deposits in the extensional-dominated accommodation spaces. |
