排山楼地区金矿控制条件分析

排山楼地区金矿化与太古宇建平群变质杂岩中的角闪质岩石，北东向，东西向断裂交汇复合部位，燕山中晚期花岗岩关系密切，研究表明：太古宇建平群大营子组，瓦子裕组原岩建造为金成矿的初始矿源层，变质作用，混合岩化作用促使金发生第２次富集；燕山中晚期岩浆活动形成热液并直接提供部分成矿物质，断裂构造为成矿物质和热液提供定位空间，金矿化受多种因素综合控制并具有多源，多期，多阶段继承性成矿特征。

ANALYSIS ON CONTROL CONDITION FOR GOLD DEPOSIT, PAISHANLOU REGION

Gold mineralization in Paishanlou region has close relations with the intersection and composite position of NE and EW trending faults, hornblendite in metamorphic complex of Archaeozoic Jianping Group and granite in the middle-late Yanshan period. The research shows that the primary source beds of gold metallization are protolith formations of Dayingzi Formation and Waziyu Formation in Archaeozoic Jianping Group. The metamorphism and migmatization made gold occur second enrichment. The middle-late Yanshanian magmatic activity formed hydrothermal fluid and directly provided section of oreforming materials. Faulted structure provided the lacation space for oreforming materials and hydrothermal fluid. Gold mineralization is comprehensively controlled by various factors and has multsource, multphase and multistage inherited metallogenic features.
