摘要
苏丹哈马迪金矿区矿石与岩石稀土配分曲线的相似性表明二者具有同源性;矿石硫同位素组成δ(34S)值为较小的负值,表明区内硫来源单一,且硫质应为深源物质;而矿石中的氢、氧同位素特征则表明金矿热液应来源于变质热液。众多事实表明,哈马迪金矿与泛非造山运动及其后的区域变质作用关系密切,成矿热液来源于围岩,属受剪切作用控制的变质热液型金矿床。
Similar REE parttern of ore and rock in Hamadi gold deposit shows that they are cognate; small negative 9（34 S）value, single source of the sulfur however H, O isotope value, hydrothermal fluid source. Various facts manifest close relation of the gold deposit to Pan-africa orogenic movement. The ore fluid is derived from the country rock and the deposit is a metamorphic hydrothermal gold deposit con- trolled by shearing.
