| 摘 要： | 辽东早元古代地层内赋存着一系列多金属硫铁矿床。矿床的形成与分布主要受裂谷盆地演化及含矿建造控制。在不同的演化阶段分别形成了含钴黄铁矿 含铜黄铁矿 含硬石膏黄铁矿矿床系列和含硼（镁电气石）磁黄铁矿 含铅锌黄铁矿 重晶石闪锌黄铁矿矿床系列。依据成矿特征可分为海底火山喷气沉积与海底喷气沉积两种成因类型。成矿作用受裂谷、次级盆地、一定含矿层位和特殊容矿岩石相互联系与配套的控矿因素制约。在对成矿规律研究的基础上将该区多金属硫铁矿划分为６个成矿远景区。

| Abstract: | The Bamiao Qingshan rutile deposit, among the country's main commercial types of rutlile deposits, has tied its origination to a titanium rich suit of rocks subjected to metamorphism. Relationship between metamorphism and mineralization, as shown by studies of mineralizing temperature and pressure, reveals that t =490.43℃, p =382MPa and reducing conditions were all very favourable for rutile precipitation. |
