陕西旬阳砂硐沟汞锑矿富集区汞锑含矿体受褶皱构造(背斜)和断裂构造的联合控制。通过对控(含)矿构造、富矿空间的构造次序以及结构面组合特征等的详细研究,对初步建立的“背斜+一刀”的成矿模式进行了完善。成矿流体、稀土分析等综合研究显示成矿物质可能来源于地壳深部。已有的勘查工程及找矿成果表明,本矿集区具有较大的找矿潜力。
Joint Control of Mercury, Antimony and Ore Bodies in the Gachangou Hg-Sb Concentrate in Xunyang, Shaanxi Province, by Fold Structure (anticline) and Fault Structure. Through the detailed study on the structure of the controlled (including) ore, the structural order of the rich ore space and the features of the structural plane combination, the initially established “anticline + one knife” metallogenic model has been improved. Comprehensive studies of ore-forming fluid, rare earth analysis show that ore-forming materials may come from the deep crust. The existing exploration works and ore prospecting results show that the ore-gathering area has a great prospecting potential.
