| 摘 要： | 瑶沟金矿床地球化学特征研究表明，主成矿因子为中偏高温元素组合（Ａｕ、Ａｇ、Ｃｕ），成矿与岩浆热动力活动有关。矿床元素垂直分带显示深部可能有盲矿体存在，水平分带表明成矿元素在热液中的运移方向为由西向东。矿体剥蚀程度为中－下部，其地球化学原生晕剥蚀程度为中－上部。据上述特征建立了矿床地球化学预测模型。

| Abstract: | The geochemical features of the Yaogou gold deposit indicates that the orthogonal factors stand for mesothermal elements(Cu,Au, Ag). Mineralization is related to magmatism. The vertical zoning of metallogenic elements indicates the existing of blind ore bodies in depth.The movement of elements from west to east is confirmed by zonation. The ore bodies have been eroded to middle-lower part,and the primary halo eroded to middle-upper part. The metallogenic prognosis model are established based on above mentioned features. |
