Abstract

Abstract—

The results of U–Pb (ID-TIMS) geochronological studies of vesuvianite from ore-bearing metasomatites of Khopunvaara ore occurrence (Pitkyaranta ore district, Northern Ladoga region) are presented. The resulting age estimate (1550 ± 6 Ma) coincides within the error with the age of formation of ore-bearing skarns that are genetically related to the rapakivi granites of the Salmi batholith. This indicates the possibility of using vesuvianite as a U–Pb mineral-geochronometer, including for ore-bearing contact-reaction rocks.

用于确定矿床年代的新型铀-铅地质年代测定矿物--维苏威岩

摘要--本文介绍了对霍蓬瓦拉（Khopunvaara）矿区（北拉多加地区皮特基亚兰塔矿区）含矿变质岩中的维苏威岩进行的铀-铅（ID-TIMS）地质年代研究结果。研究得出的年龄估计值（1550 ± 6 Ma）与含矿矽卡岩的形成年龄在误差范围内相吻合，而含矿矽卡岩在遗传学上与萨尔米浴成岩的拉帕基维花岗岩有关。这表明有可能使用蔷薇岩作为 U-Pb 矿物测时计，包括含矿接触反应岩。
