The 18 × 4 km Davenda-Klyuchevskoe cluster in the Mogocha mineral district of the Siberian craton hosts gold, silver, molybdenum and copper in six types of mineralization. The general sulphide zoning at the Sergeevskoe and Klyuchevskoe deposits, the largest in the cluster, is similar to porphyry systems, but the orebodies form 4.5 × 1 km multiple linear sulphide-rich quartz-veinlet swarms, rather than a bulk mineralized envelope. Five types of mineralization formed at 162 − 150 Ma. They are clearly overprinted by northeast-striking epithermal Au-Ag carbonate-quartz veins. All mineralization is genetically linked to the Peak Klyuchi subvolcanic centre of Late Jurassic to Early Cretaceous age (159 − 132 Ma) which is part of the Amudzhikan intrusive complex, consisting of early complexly shaped ENE-striking granodiorite porphyry stock and dykes, intruded by magmatic to hydrothermal breccia and five generations of WNW-trending dykes of dioritic porphyry, hybrid porphyry, rhyolite, and ultimate lamprophyre. The dykes control or parallel five types of megastockwork orebodies within a dextral extensional strike-slip duplex. However, Au-Ag epithermal veins follow late-mineral northeast faults, dividing the megastockwork into several domains. The Davenda-Klyuchevskoe cluster is part of the Shilka Mo-(Au-Ag-Cu) metallogenic belt, striking within the Siberian craton just 25 km north in parallel to the Mongol-Okhotsk suture. Geochronological and petrological data suggest that the intrusive complex and its mineralization formed in relation to northward-dipping subduction prior to scissor-like suturing in this segment of the Mongol-Okhotsk Ocean in response to the northward push by the North China and Yangtze cratons towards Siberia.

位于西伯利亚克拉通 Mogocha 矿区的 18 × 4 km Davenda-Klyuchevskoe 星团蕴藏着金、银、钼和铜的六种矿化类型。该矿团中最大的 Sergeevskoe 和 Klyuchevskoe 矿床的总体硫化物分带与斑岩系统相似，但矿体形成 4.5 × 1 km 的多个线性富含硫化物的石英细脉群，而不是块状矿化包层。五种类型的矿化形成于 162 – 150 Ma。它们明显被东北走向的浅成热液金银碳酸盐石英脉所覆盖。所有矿化都与侏罗纪晚期到白垩纪早期（159 - 132 Ma）的 Klyuchi 峰地下火山中心有关，该中心是 Amudzhikan 侵入杂岩的一部分，由早期复杂形状的 ENE 撞击花岗闪长斑岩岩浆和岩脉组成，被岩浆侵入热液角砾岩和五代西北西向闪长斑岩、混合斑岩、流纹岩和终极煌斑岩岩脉。岩脉控制或平行于右旋伸展走滑复式矿体内的五种巨型网状矿体。然而，金银浅成热液脉沿着晚期矿物东北断层延伸，将巨型网状体系划分为几个区域。 Davenda-Klyuchevskoe 星团是石勒喀钼（金银铜）成矿带的一部分，位于西伯利亚克拉通以北仅 25 公里处，与蒙古-鄂霍次克缝合线平行。地质年代学和岩石学数据表明，侵入杂岩及其矿化的形成与蒙古-鄂霍次克洋这一段剪刀状缝合之前向北倾斜的俯冲有关，响应华北和扬子克拉通向西伯利亚的北推。
