ABSTRACT U–Pb dating of detrital zircons collected from the Middle–Upper Palaeozoic strata of the Prikolyma terrane (Verkhoyansk–Kolyma orogen) provide the first insight into provenance areas and the Middle–Late Palaeozoic geological history of the Russian Far East. Detrital zircon ages from the Lower–Middle Devonian sandstones group around 395–405 M (Emsian–Eifelian) which correlate well to trachyte of the Uvyazka zone and the Kedon Complex of the North Okhotsk active continental margin located on the Omolon terrane. Precambrian-aged zircons group around 1740–2080 and 2460–2800 Ma, respectively, suggesting possible sources within metamorphic rocks of the basement of the Omolon terrane or the Siberian Craton. The majority of the zircons from the Lower and Upper Carboniferous sandstones group around 333–375 Ma, suggesting that the principle source of the clastics were volcanic rocks and comagmatic felsic intrusions of the Kedon Complex of the North Okhotsk active continental margin. Our new data allow us to evaluate and revise the available palaeotectonic reconstructions of northeast Asia for the Devonian and Carboniferous.

基于碎屑锆石 U-Pb 定年的 Prikolyma 地体（Verkhoyansk-Kolyma 造山带）南部泥盆纪-石炭纪碎屑物的来源

摘要 从 Prikolyma 地体（Verkhoyansk-Kolyma 造山带）中上古生界地层收集的碎屑锆石的 U-Pb 定年提供了对俄罗斯远东地区和中晚古生代地质历史的首次了解。来自下-中泥盆统砂岩群的碎屑锆石年龄大约在 395-405 M（Emsian-Eifelian），与位于 Omolon 地体的 Uvyazka 带粗面岩和北鄂霍次克活动大陆边缘的 Kedon 杂岩很好地相关。前寒武纪锆石群分别在 1740-2080 和 2460-2800 Ma 左右，表明 Omolon 地体或​​西伯利亚克拉通基底的变质岩中可能存在来源。下石炭统和上石炭统砂岩的锆石大部分分布在 333-375 Ma 左右，表明碎屑的主要来源是鄂霍次克北部活动大陆边缘的克顿杂岩的火山岩和长英质岩浆侵入体。我们的新数据使我们能够评估和修订东北亚泥盆纪和石炭纪可用的古构造重建。
