摘要: 烂木沟金矿位于陕西省旬阳县境内,产于南秦岭石泉-神河构造岩片中,受黑虎庙脆-韧性剪切带控制。文章通过烂木沟金矿区域成矿背景、地质特征及矿床地球化学分析,初步探讨了烂木沟金矿床成因。烂木沟地区地层中黄铁矿微量元素Co含量为67.60×10-6~208.00×10-6,Ni含量108.00×10-6~585.00×10-6,稀土元素总量2.16×10-6~22.90×10-6,矿石黄铁矿中Co含量为317.00×10-6~751.00×10-6,Ni含量82.80×10-6~304.00×10-6,稀土元素总量4.04×10-6~51.74×10-6,矿石黄铁矿中δ34S值为9.9‰~12.9‰,均值11.27‰,矿石黄铁矿中铅同位素206Pb/204Pb值为18.560~20.206,207Pb/204Pb值为15.668~15.708,208Pb/204Pb值为38.257~38.860,地层黄铁矿中铅同位素206Pb/204Pb值为18.502~20.086,207Pb/204Pb值为15.644~15.788,208Pb/204Pb值为38.475~38.907,矿石中石英的δ18OV-SMOW值为13.5‰~15.9‰,均值为14.7‰,δDV-SMOW值为-77.8‰~-71.3‰,均值为-74.55‰,矿石中黄铁矿Re-Os等时线年龄202±12 Ma。结论认为烂木沟金矿成矿物质来源于地层中火山岩夹层,成矿流体为多来源,主体为建造水改造后的变质水。烂木沟金矿形成于晚三叠世末期—早侏罗世早期秦岭造山带碰撞后的伸展阶段,成矿流体充填于脆-韧性剪切带片理中,矿物沉淀富集,为造山型金矿。Abstract: The Lanmugou gold deposit is located in Xunyang County, Shaanxi Province, produced in the Indosinian Shiquan-Shenhe thrust nappe of the South Qinling, and controlled by the Heihumiao brittle-ductile shear zone. In this paper, via the analysis of the mineralization background, ore-controlling structure features and geochemical characteristics of the deposit, the preliminary conclusions on the geological characteristics and metallogenesis of the Lanmugou gold deposit have been obtained. Co content of pyrite in strata varies from 67.6×10-6 to 208×10-6, Ni content from 108×10-6 to 585×10-6, and the total amount of rare earth elements from 2.16×10-6 to 22.9×10-6. Simultaneously, Co content in hydrothermal pyrite varies from 317×10-6 to 751×10-6, Ni content from 82.8×10-6 to 304×10-6, and the total amount of rare earth elements from 4.04×10-6 to 51.74×10-6. δ34S value in hydrothermal pyrite ranges from 9.9‰ to 12.1‰, with the average value of 11.27‰. 206Pb/204Pb value of hydrothermal pyrite ranges from 18.560 to 20.206, 207Pb/204Pb value from 15.668 to 15.708, 208Pb/204Pb value from 38.257 to 38.860; 206Pb/204Pb value of pyrite in the strata ranges from 18.502 to 20.086, 207Pb/204Pb value from 15.644 to 15.788 and 208Pb/204Pb value from 38.475 to 38.907. δ18OV-SMOW value of quartz in ore ranges from 13.5‰ to 15.9‰, with the average value of 14.7‰, and the δDV-SMOW value ranges from -77.8‰ to -71.3‰, with the average value of -74.55‰. Re-Os isochron age of pyrite in the ore is 202±12 Ma. From the comprehensive studies, it is concluded that the source of ore-forming materials of the Lanmugou gold deposit is from the interlayer of volcanic rocks in strata, and the ore-forming fluids are multiple-sourced (basically metamorphic water derived from interlayer water, atmospheric precipitation). The inference of metallogenesis is that the ore-forming hydrothermal fluids filled the lamellae of brittle-ductile shear zone and the minerals were precipitated and enriched in the extension stage after the collision of the Qinling orogenic belt at the end of the late Triassic-early Jurassic. The metallogenic characteristics show that the Lanmugou deposit is an orogenic gold deposit.
