中文摘要：

氦，铅和硫同位素组成上的研究 Gejiu 超级大的 Sn-polymetallic 矿床被执行。结果显示形成矿石的材料来自不同来源和存款是附加矿化作用的一个产品。存款被多来源和多时期矿化作用描绘，它经历了海底的热水的免职和迟了的 Yanshanian magmatic 热水的矿化作用。Gejiu 超级大的 Sn-polymetallic 矿床是多开始存款，这被保持。

英文摘要：

Studies on the helium, lead and sulfur isotopic composition were performed of the Gejiu super-large Sn-polymetallic ore deposit. The results indicated that the ore-forming materials came from different sources and the deposit is a product of superimposed mineralization. The deposit is characterized by multi-source and multi-period mineralization, which experienced submarine hydrothermal deposition and Late Yanshanian magmatic hydrothermal mineralization. It is held that the Gejiu super-large Sn-polymetallic ore deposit is a multi-genesis deposit.
