通过野外调查采样和测试分析,对贵州黔东镇远金堡铅锌矿床开展碳、氧、硫同位素地球化学特征等进行研究,方解石和白云石碳同位素在-5.7‰~-6.9‰,落在典型的火成碳酸岩区域(-5‰~-7‰);氧同位素在11.2‰~12.2‰之间,略高于火成碳酸岩,预示火成碳酸岩物质经过低温蚀变造成氧同位素偏高。闪锌矿硫同位素分布较为集中,在11.5‰~14.2‰之间,结合该区域的碳同位素,暗示成矿物质来自于深部地幔或岩浆作用。通过碳-氧稳定同位素示踪分析,结合区域地质条件及矿床地质特征研究,认为金堡铅锌矿成矿热液与岩浆作用有关,
Through field survey, sampling and test analysis, the carbon, oxygen and sulfur isotopic geochemical characteristics of Yuanjinbao lead-zinc deposit in Qiandong Town, Guizhou Province were studied. The carbon isotopes of calcite and dolomite ranged from -5.7 ‰ to -6.9 ‰, (-5 ‰ ~ -7 ‰). The oxygen isotope is between 11.2 ‰ and 12.2 ‰, which is slightly higher than that of igneous carbonate rocks, which indicates that the oxygen isotopes are high after low temperature alteration of igneous carbonates . Sulfur isotope distribution of sphalerite is relatively concentrated, ranging from 11.5 ‰ to 14.2 ‰, combining carbon isotopes in this area, indicating that the ore-forming materials come from deep mantle or magma. Through carbon-oxygen stable isotope tracing analysis, combined with regional geological conditions and geological characteristics of deposits, it is considered that the Jinbao lead-zinc mineralization hydrothermal fluid is related to magmatic activity,
