Abstract

The results of U–Pb geochronological (SIMS) study of zircons from granitoids of the Konstantinovskii Stock located 6 km from the Sukhoi Log gold deposit are reported. The ²⁰⁶Pb/²³⁸U weighted average age for long-prismatic crystals, rims, and cores of the early stage of crystallization of zoned zircons is 303 ± 3 Ma (MSWD = 0.87). The data obtained on the age of xenogenic cores of zoned zircons of the Konstantinovskii Stock granitoids indicate consolidated basement of the Bodaibo epicratonic sedimentary basin and its intraplate tectono-thermal transformation in the Archean, Paleoproterozoic and Paleozoic.

Konstantinovskii储层（苏霍伊原木金矿床地区）的花岗岩类锆石（SIMS）的研究结果：年龄，来源和地质后果

摘要

据报道，在距苏霍伊原木金矿床6公里处的康斯坦丁科夫斯基储层花岗岩类锆石中的锆石进行U–Pb地质年代学（SIMS）研究。区域锆石早期结晶的长棱柱形晶体，边缘和核的²⁰⁶ Pb / ²³⁸ U加权平均年龄为303±3 Ma（MSWD = 0.87）。关于康斯坦丁科夫斯基花岗岩类带状锆石的异种岩心年龄的数据表明，在太古代，古元古代和古生代，博代博Epicratonic沉积盆地的基底已经固化，板内构造热转换。
