| 摘 要： | 排山楼大型金矿床产于辽酉高级变质太古宙花岗岩－绿岩带中，受绿岩中、上部层位的基性－中酸性火山岩系和东西向韧性剪切带控制。容矿岩石主要是变安山质－英安质火山岩类。金矿围岩蚀变强烈。蚀变作用具分带性，从外带到内带可分为绿泥石化带、碳酸盐化带和黄铁矿－绢云母化带，各带之间没有明显界线。矿体与黄铁矿－绢云母化带关系密切。金矿石为矿化糜棱岩，主要金属矿物为黄铁矿和磁黄铁矿，金矿物为自然金。中深层次的韧性剪切作用为主要成矿作用，控制了矿体的就位空间和时间。

| Abstract: | Paishanlou large gold deposit occurs in western Liaoling Archean granite -greenstone belt which subjected to high - grade metamorphism. Gold mineralization wascontrolled by basic - midium -- accidic volcanics of the middle - upper levels in the greenstonesequence and by EW striking ductile shear zones. The host-rocks mainly are meta - andesiticdacitic volcanic rocks. In the gold ore zone, the rocks are stoogely experienced with alterationshowing zonal pattern, from outer to inner zone, successively appearing chloritization,carbonization, and pyritic - sericitization. But boundary between them are not clear. Orebodiesare limited to the ductile shear zone, and are closely related to the pyritisericitization. Gold oresare gold - bearing alterated mylonites. The main metallic minerals are pyrites and pyryhotieds,gold minerals are mainly natural gold. The metallogenic process maialy were closely related to theductile shearing within middle - deep level, that controlled the ore - forming space and time. Theductile shearing process began from the Early Proterozoic Era and ended to Yenshan ongenicmovement. Therefore, the metallogenic process occurred within relative long time span, but, themajor mineralization probably occurred in early proterosoic era. |
