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。
The Yangjialing Au-A-Sb deposit is located in the fine-detritus-carbonate rock formation of the Zhenan-Xunyang basin in the Indosinian fold belt of the Qinling System, and has undergone three tectono-hydrothermal activities. This paper focuses on the distribution, distribution, symbiotic assemblages of trace elements in different geologic units and the chemical composition of fluid inclusions. Combined with the analysis of metallogenic conditions, it is considered that the ore bodies are controlled by both the stratum and the fault structure, and the structure is the main controlling factor. Antimony ore bodies occur in the favorable structural parts of the Yuanjiagou limestone, gold mineralization is not significant, the formation of Nanyangshan Formation gold ore possible.
