Abstract

The Iron Oxide Copper-Gold (IOCG) deposit class includes a number of loosely related deposits with a pool of common characteristics. The Kis-Kuel intrusion-related IOCG deposit in Eastern Yakutia (Russia) with a wide range of mineral styles has a direct genetic link with a cooling intrusion during its formation. The IOCG and the Kis-Kuel have common features for this style - the abundance of iron oxides and low of sulfides. Magmatic contribution to the Kis-Kuel deposit is significant. Intrusive rocks range from diorite to granodiorite in composition. Rare-earth geochemical system of igneous rocks of the Kis-Kuel intrusive is characterized by behavior close to the CHArge-and-RAdius-Controlled CHARAC-system (26

东雅库特ki - kuel Fe-Cu-Au±(Ag, Mo, Bi)矿床——氧化铁铜金与侵入相关金系统的联系

氧化铁铜金(IOCG)矿床类别包括许多具有共同特征的松散关联矿床。俄罗斯东部雅库特地区与kiskuel侵入有关的矿物类型广泛的IOCG矿床，其形成与冷却侵入有直接的成因联系。IOCG和kiss - kuel具有这种风格的共同特征-氧化铁丰富而硫化物含量低。岩浆对kiskuel矿床的贡献是显著的。侵入岩的成分从闪长岩到花岗闪长岩不等。kiss - kuel侵入岩的稀土地球化学系统具有接近电荷-半径控制的特征(26
