粤北瑶岭-梅子窝钨矿成矿阶段形成的黄铁矿等矿物流体包裹体的He和Ar同位素丰度及比值分析表明,其4He的含量变化大,为(1.54～2609)×107cm3STP/g,3He的含量为(0.759～3.463)×1012cm3STP/g,3He/4He的比值为0.0043～4.362Ra,介于幔源与壳源He之间;40Ar含量为(0.624～8.89)×107cm3STP/g,40Ar/36Ar比值变化大,在330～2952之间,介于大气氩与壳源或幔源放射性成因氩之间.成矿流体中有幔源He的加入,幔源He的平均含量为22%,最高可达67%,显示幔源流体在成矿过程中起了重要的作用;He和Ar同位素分异说明除幔源流体参与成矿外,富含4He的壳源改造型饱和大气水参与了成矿,成矿流体为幔源流体、壳源岩浆流体和改造型饱和大气水以不同比例混合的流体.幔源流体参与成矿表明,华南燕山中期(约150～160Ma)包括瑶岭-梅子窝钨矿在内的大规模的W,Sn成矿作用是壳幔相互作用的结果.
He and Ar isotopic abundance and ratio analysis of mineral inclusions in pyrite formed during the ore-forming stage of the Yao-Ling-Meizivow tungsten deposit in northern Guangdong show that the content of 4He varied greatly from (1.54 to 2609) × 107cm3STP / g, the content of 3He is (0.759 ~ 3.463) × 1012cm3STP / g and the ratio of 3He / 4He is 0.0043 ~ 4.362Ra, which is between the mantle source and the He source. The 40Ar content is (0.624 ~ 8.89) × 107cm3STP / g , The ratio of 40Ar / 36Ar varies greatly, ranging from 330 to 2952, between the atmospheric argon and the crustal or mantle source radiogenic argon. The addition of mantle He to the ore-forming fluid has an average content of mantle He %, Up to 67%, indicating that mantle-derived fluids played an important role in the metallogenesis. The isotope differences of He and Ar indicate that except for the involvement of mantle source fluids, 4He-enriched shell-sourced saturated atmospheric water The mineralization and ore-forming fluids are mantle-derived fluids, crust-derived magmatic fluids and modified saturated atmospheric water mixed with fluids in different proportions.The mantle-derived fluids involved in mineralization indicate that the mid-Yanshanian (about 150-160 Ma) The large-scale W and Sn mineralization, including the plumbago tungsten deposit, is the result of crust-mantle interaction.
