摘要

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.
