The Talnikovoye ore field, where previous academic research and exploration works revealed porphyry copper mineralization, is described. Our data show that the mineralization is confined to the Turonian granodiorite and quartz diorite intrusions (91 Ma, U–Pb metohod) and accompanying hydrothermal–explosive breccias. Biotite–epidote–chlorite propylites are widespread within the ore field; in the southern part, quartz–sericite phyllic alteration is superimposed on the K-feldspar alteration halo. The ore occurs in zones of intense quartz, chlorite–epidote–quartz (with chalcopyrite and molybdenite), sulfide-potassium feldspar–quartz (with chalcopyrite and bornite), and sulfide–quartz–sericite (with chalcopyrite) stockwork veining with copper–molybdenum mineralization. They have moderate concentrations of Cu (0.1–0.3%, reaching 1.1%) and Mo (up to 0.1%), low concentrations of Au (up to 0.1 g/t) and Ag (up to 2.6 g/t), and have a Cu–Mo–(Au, Ag, Pb, Zn, Sb, and As) geochemical signature. Fluid inclusion data suggest the formation of quartz in mineralized veinlet during the magmatic–hydrothermal transition (430–150°С) with solutions at high (50 wt % NaCl equiv.), medium and low concentrations (5–18.9 wt % NaCl equiv.) involved under the cooling–dilution scenario. The values of the main geochemical indicators, such as Cu/Mo (30–60) and Cu/Au (>1 × 10⁵) ratios allowed us to assign the Talnikovoye ore field to the porphyry copper–molybdenum type characteristic of continental-margin volcano-plutonic belts formed on the mafic island-arc basement. The geochemical parameters of ore-bearing porphyry granitoids indicate their formation in a setting of a subduction-to-transform plate boundary transition.

描述了塔尔尼科沃耶 (Talnikovoye) 矿田，之前的学术研究和勘探工作揭示了斑岩铜矿化。我们的数据表明，矿化仅限于土伦阶花岗闪长岩和石英闪长岩侵入体（91 Ma，U-Pb 方法）以及伴随的热液-爆炸角砾岩。黑云母-绿帘石-绿泥石丙岩广泛存在于矿田内；在南部，石英-绢云母蚀变叠加在钾长石蚀变晕之上。矿石产于强石英、绿泥石-绿帘石-石英（含黄铜矿和辉钼矿）、硫化钾长石-石英（含黄铜矿和斑铜矿）和硫化物-石英-绢云母（含黄铜矿）、含铜-钼的网脉带中。矿化。它们含有中等浓度的铜（0.1-0.3％，达到1.1％）和钼（高达0.1％），低浓度的金（高达0.1克/吨）和银（高达2.6克/吨），并且具有Cu-Mo-（Au、Ag、Pb、Zn、Sb 和 As）地球化学特征。流体包裹体数据表明，在岩浆-热液转变（430-150°С）期间，在高浓度（50 wt% 氯化钠当量）、中浓度和低浓度（5-18.9 wt% 氯化钠当量）溶液中，矿化细脉中形成了石英。 ）涉及冷却稀释场景。主要地球化学指标，如Cu/Mo（30~60）和Cu/Au（>1×10 ⁵）比值，使我们能够将Talnikovoye矿田划定为陆缘斑岩铜钼型特征。火山-深成带形成于镁铁质岛弧基底上。含矿斑岩花岗岩的地球化学参数表明它们是在俯冲-转变板块边界过渡的背景下形成的。
