摘要
长江中下游成矿带是我国重要的成矿区带,栖霞山铅锌银多金属矿床规模巨大,品位富,是我国一个重要的铅锌矿区.选取与主成矿期有关的黄铁矿进行原位微量元素和硫同位素的测定.结果显示,黄铁矿δ34S值的变化不大,分布范围为+4. 16‰～-5. 51‰,平均值为+0. 38‰,为单一岩浆来源.黄铁矿中硫低于标准值,有亏损现象,也证明其为岩浆热液来源.
The Middle-Lower Yangtze River Valley Metallogenic Belt is an important metallogenic belt in China. The Qixiashan Pb-Zn-Ag polymetallic deposit is large scale and rich in grade. It is an important lead-zinc deposit in China. In situ trace elements and sulfur isotopes were conducted on the pyrite associated with the main mineralization period. The results show that the δ^34S value of pyrite does not change much, ranging from ＋4.167 to -5.517, with an average value of ＋ 0.387, which is a single magma source. Sulfur in pyrite is lower than the standard value and there is a loss phenomenon, which also proves that it is a source of magmatic-hydrothermal fluid.
