摘    要：杨家岭金汞锑矿床位于秦岭地槽系的南秦岭印支褶皱带镇安—旬阳盆地细碎屑-碳酸盐岩建造中,经历了3个构造-热液活动阶段。重点探讨了微量元素在不同地质单元的分布、分配、共生组合以及流体包裹体化学成分特征,结合成矿条件分析,认为矿(化)体受地层和断裂构造双重控制,构造为主要控制因素,锑矿体赋存于有利构造部位的袁家沟组灰岩中,金矿化发育不显著,南阳山组地层有形成金矿体的可能。

Abstract: Yangjialing Au-Hg-Sb deposit locates in fine clastic and carbonate rocks of Zhen’an-Xunyang basin in the South Qinling Indo-fold belt of Qinling geosynclinal system.The deposit experienced 3 structure-hydrothermal fluid operation phase.The distribution,assignment and combination of microelement in different geological unions and chemical component characteristics of fluid inclusion are discussed in detailed.It is concluded that orebodies are controlled by stratum and faults,which is the main controlling factor.Sb orebodies locate in Yuanjiagou group limestone,which is the advantageous structure part.The gold mineralization is not remarkable and Nanyangshan group stratum may exist gold orebodies.
