| 摘 要： | 宁芜地区属于长江中下游多金属成矿带的中部 ,产有多处黄铁矿矿床 ,一些已达到大型矿床规模。它们形成的地质环境具有显著的火山热水沉积成矿特征。充足的物质来源、巨大的热源、热水系统演化的完整性、成矿盆地极好的封闭性和同沉积期构造发育等 ,为黄铁矿矿床的形成提供了有利条件。

| Abstract: | Nanjiang Wuhu district, the meddle segment of the metallogenic zone along the middle lower reaches of Yangtze river, is rich in pyrite mineralizations, some of which may be labeled as large sized. Geological conditions for the mineralizations bear a marked brand of hotwater deposition concerning volcanic activities, with adequate material source, complete evolution of hotwater systems, perfect closure of sedimentary basins and development of synsedimentary structures. All this is necessary for formation of the pyrite deposits. |
