| 摘 要： | 河南庄金矿位于华北板块最南端的秦岭构造带上，赋矿围岩为一套碳酸盐岩钙泥质建造，矿化受地层和构造发育控制.通过微量元素、稀土元素、C-H-O-S同位素分析对成矿流体来源和成矿条件进行了研究.其中微量元素、稀土元素、氢-氧同位素分析都指示成矿流体来自岩浆，后期受到变质作用和沉积改造作用影响；碳-氧同位素数据表明碳和部分氧元素来自海相碳酸盐的溶解作用，并催化了金元素的富集；硫同位素与微量元素分析得出成矿环境为缺氧的还原环境，并指示成矿流体来自深地壳或地幔.河南庄金矿同蚀变岩型金矿的矿床地质-地球化学特征相似，应属于蚀变岩型金矿.

| Abstract: | The Henanzhuang Gold Deposit is located on the Qinling tectonic belt in southernmost North China Plate with the host rock of a set of calc-muddy carbonate rock formation. The mineralization is controlled by strata and structure. The sources and metallogenic conditions of ore-forming fluid are studied by analyzing the trace, rare earth elements and C-H-O-S isotopes. The results show that the ore-forming fluid derived from magma is affected by later metamorphism and sedimentary reformation. The C and partial O elements come from the dissolution of marine carbonate, and catalyze the enrichment of Au. The S isotope and trace elements data indicate the deposit was formed in the anoxic reducing environment with the ore-forming fluid derived from deep crust or mantle. The geological and geochemical characteristics of the Henanzhuang Gold Deposit are similar to those of altered rock-type gold deposits, thus it should be classified as the latter. |
