This paper reports the results of a study of magmatic rocks with Sn–W–Au–Ag mineralization from the Kuranakh, Elikchan, and Istekh ore fields in the Northern batholith belt of the north-eastern Verkhoyansk–Kolyma orogenic belt in Eastern Russia. Using petrographic, mineralogical, geochemical, and isotopic methods, we determined the mineral compositions, petrochemistry, and geochemistry of magmatic rocks, the P–T conditions of their generation and crystallization, and their geodynamic affinity. The studied magmatic rocks have common geochemical characteristics that likely reflect the influence of fluids supplied from a long-lived, deep-seated mantle source. The ore fields are characterized by Sn–W–Au–Ag–Pb polygenetic mineralization. The magmatic and metallogenic evolution comprised five stages for the formation of magmatic rocks and ores. During the first stage (Berriasian–Barremian), arc-related magmatic rocks formed in an active continental margin setting and were associated with Au–Ag mineralization. The second, third, and fourth stages (Aptian–Campanian) took place in a crustal extension and rift setting, and were accompanied by Au–Ag and Sn–W mineralization. During the fifth (post-magmatic) stage, Sn–Ag–Sb and Pb–Ag mineralization occurred.

俄罗斯东北Verkhoyansk-Kolyma造山带含复杂Sn-Au-Ag矿化的含矿岩浆系统

本文报道了俄罗斯东部Verkhoyansk-Kolyma造山带东北部基岩带的Kuranakh，Elikchan和Istekh矿田中Sn-W-Au-Ag矿化岩浆岩的研究结果。使用岩相学，矿物学，地球化学和同位素方法，我们确定了岩浆岩的矿物成分，岩石化学和地球化学，岩浆岩生成和结晶的PT条件以及它们的地球动力学亲和力。被研究的岩浆岩具有共同的地球化学特征，可能反映了长期存在的深部地幔源流体的影响。矿田的特征是Sn–W–Au–Ag–Pb多矿成矿作用。岩浆和成矿作用的演化包括形成岩浆岩和矿石的五个阶段。在第一阶段（Berriasian–Barremian），与弧有关的岩浆岩在活跃的大陆边缘环境中形成，并与Au-Ag矿化有关。第二阶段，第三阶段和第四阶段（阿普特－坎帕干）发生在地壳伸展和裂谷环境中，并伴有金－银和锡－钨矿化作用。在第五（岩浆后）阶段，发生了Sn-Ag-Sb和Pb-Ag矿化。
