The authors' determinations of the U–Pb isotopic age of zircon (LA–ICP–MS method) in the main types of igneous rocks emphasize the presence of both Neogene and older (up to Late Paleozoic) intrusions at the deposit. The earliest are rocks of the “trondhjemite” massif, which were emplaced in the Late Paleozoic. This age of the rocks of the trondhjemite massif, confirmed by the U–Pb isotopic method (302 ± 4 Ma) for zircon from rocks of its main intrusive phase (tonalites–granodiorites), is consistent with manifestation of Late Paleozoic tungsten-bearing magmatism and associated W mineralization in the North Caucasus (in the Peredevoi Range) and allows a possible Late Paleozoic age of large bodies of altered skarns with W mineralization at the Tyrnyauz deposit. At the next, Neogene stage, the intrusion of leucocratic granites took place with the formation of bodies of igneous breccias, the emplacement of an accompanying aplite dike formation, and the development of intense molybdenum (with subordinate W) mineralization in large vein–veinlet, stockwork systems. The U–Pb isotopic age of zircon in leucocratic granites is 2.67 ± 0.04 Ma. Later, a large massif of biotite (Eldzhurt) granites and associated formation of aplite and alaskite dikes were formed. Emplacement of subvolcanic rhyolite bodies followed. The U–Pb isotopic age of zircon in the Eldzhurt granites is 2.10 ± 0.08 Ma, and in rhyolites, 2.05 ± 0.04 Ma. Intrusion of these rocks was accompanied by the formation of Mo–W–Bi–Te–Au mineralization.

作者对主要类型火成岩中锆石的 U-Pb 同位素年龄（LA-ICP-MS 方法）的测定强调了该矿床中存在新近纪和较旧的（直至晚古生代）侵入体。最早的为晚古生代的“长闪长岩”地块岩石。用 U-Pb 同位素方法 (302 ± 4 Ma) 确定其主要侵入相岩石（方长岩-花岗闪长岩）中锆石的这一年龄与晚古生代含钨岩浆作用的表现相一致和北高加索（在 Peredevoi 山脉）的伴生 W 矿化，并允许 Tyrnyauz 矿床中带有 W 矿化的大型蚀变矽卡岩体可能存在晚古生代时代。在下一个新近纪阶段，白晶花岗岩的侵入伴随着火成岩角砾岩体的形成、伴随的 aplite 岩脉形成的侵位，以及在大的脉-脉、网状系统中形成强烈的钼矿化（具有从属 W）。白斑花岗岩中锆石的 U-Pb 同位素年龄为 2.67 ± 0.04 Ma。后来，形成了大量的黑云母 (Eldzhurt) 花岗岩以及与之相关的 aplite 和 alaskite 岩脉。随后发生了次火山流纹岩体的就位。Eldzhurt 花岗岩中锆石的 U-Pb 同位素年龄为 2.10 ± 0.08 Ma，流纹岩中为 2.05 ± 0.04 Ma。这些岩石的侵入伴随着 Mo-W-Bi-Te-Au 矿化的形成。以及在大脉-脉、网状系统中形成强烈的钼（含 W 下级）矿化。白斑花岗岩中锆石的 U-Pb 同位素年龄为 2.67 ± 0.04 Ma。后来，形成了大量的黑云母 (Eldzhurt) 花岗岩以及与之相关的 aplite 和 alaskite 岩脉。随后发生了次火山流纹岩体的就位。Eldzhurt 花岗岩中锆石的 U-Pb 同位素年龄为 2.10 ± 0.08 Ma，流纹岩中为 2.05 ± 0.04 Ma。这些岩石的侵入伴随着 Mo-W-Bi-Te-Au 矿化的形成。以及在大脉-脉、网状系统中形成强烈的钼（含 W 下级）矿化。白斑花岗岩中锆石的 U-Pb 同位素年龄为 2.67 ± 0.04 Ma。后来，形成了大量的黑云母 (Eldzhurt) 花岗岩以及与之相关的 aplite 和 alaskite 岩脉。随后发生了次火山流纹岩体的就位。Eldzhurt 花岗岩中锆石的 U-Pb 同位素年龄为 2.10 ± 0.08 Ma，流纹岩中为 2.05 ± 0.04 Ma。这些岩石的侵入伴随着 Mo-W-Bi-Te-Au 矿化的形成。随后发生了次火山流纹岩体的就位。Eldzhurt 花岗岩中锆石的 U-Pb 同位素年龄为 2.10 ± 0.08 Ma，流纹岩中为 2.05 ± 0.04 Ma。这些岩石的侵入伴随着 Mo-W-Bi-Te-Au 矿化的形成。随后发生了次火山流纹岩体的就位。Eldzhurt 花岗岩中锆石的 U-Pb 同位素年龄为 2.10 ± 0.08 Ma，流纹岩中为 2.05 ± 0.04 Ma。这些岩石的侵入伴随着 Mo-W-Bi-Te-Au 矿化的形成。
