通过氢、氧、铅同位素和流体包裹体测试,结合争光金矿床的地质、微量元素、稀土元素地球化学特征研究,表明争光金矿为岩浆低温热液矿床。成矿物质主要来源于地层,矿化类型为蚀变岩型和石英脉型。成矿流体为岩浆水、变质水和大气降水的混合液。δD值为-63‰~-85‰,1δ8O水值为-0.2‰~-7.0‰,主成矿阶段温度为133~276℃。
Through the hydrogen, oxygen, lead isotopes and fluid inclusions testing, combined with the Geological, trace elements, rare earth element geochemical characteristics of the Zhengguang gold deposit, it shows that the Zhengguang gold deposit is a magmatic low temperature hydrothermal deposit. The ore-forming materials mainly come from the strata, and the mineralized types are altered rock type and quartz vein type. The ore-forming fluid is a mixture of magmatic water, metamorphic water and atmospheric precipitation. The δD values ranged from -63 ‰ to -85 ‰, the 1δ8O water values ranged from -0.2 ‰ to -7.0 ‰, and the main mineralization stages were from 133 to 276 ° C.
