| 摘 要： | 中川地区载金矿物硫同位素、氢氧同位素和碳氧同位素特征说明成矿作用与沉积建造有较大的亲缘性。载金矿物流体包裹体中大量的 Cl- 、SO4 2 - 和 Ca2 、Na 高含量及其特征比值显示出大气降水带入了大量的建造中的物质成分。热液期黄铁矿微量元素标型特征体现地下热卤水溶滤成因特征 ,同时也显示了岩浆活动对成矿作用影响的痕迹

| Abstract: | The characteristics of sulphur isotope, hydrogen oxygen isotope and carbon oxygen isotope of gold carrying minerals in zhongcuan region show that mineralizartion has a close affinity with sedimentary formation High contents of Cl , SO 2 4 and Ca 2 , Na and its particular ratios in fluid inclusions of gold carrying minerals indicate that meteoric water brought large quantity of matters from the formations Typomorphic characteristics of trace elements of pyrite of hydrothermal period reflect the genetic character of underground hot brine leaching and the trace left by the influence of magma activities on ore forming process |
