吉林延边金谷山金矿床地球化学特征

Geochemical features of Jingushan gold deposit in Yanbian,Jilin province

以金谷山金矿床的成矿地质特征为基础,研究了区域地球化学场及异常特征、岩(矿)石微量元素地球化学特征。矿床位于金及其它成矿元素的高背景场中,与成矿有关的元素组合为Au-Sb-As,异常强度高,分带性明显;地层、岩浆岩、构造等地质单元的地球化学特征表明,成岩作用、构造作用与成矿作用关系密切。

Based on the metallogenic geological features in Jingushan gold deposit, the regional geochemical fields, anomaly characteristics and rock （ore） trace elements geochemical features are studied. The deposit locates in the high background field of gold and other ore-forming elements, with the ore-forming elements combination of Au- Sb-As. The anomaly intensity is high and the zoning is obvious. The geochemical characteristics of formation, magmatic rocks, tectonic and other geological units indicate that the relationship among diagenesis, tectonism and mineralization is close.
