Age of Gabbrodolerites of Belarus “Big Dike”: Results of Baddeleyite U–Pb (ID-TIMS) Geochronological Studies

Key Points

This research aims to date the gabbrodolerites of the Big Dike in Belarus through geochronological methods.
Conducted U–Pb geochronological studies using ID-TIMS technique on baddeleyite.
Sampled basic rocks from the Big Dike located in the crystalline basement of Belarus.
The age of the gabbrodolerites is determined to be 1788 ± 4 Ma.
This age corresponds to the final events of the Subbotka-Moshorin deformation stage, dating from 1788 to 1792 Ma.

Abstract

This work report on dating of the basic rocks of the “Big Dike” located in the south-eastern part of the crystalline basement of Belarus. U–Pb (ID-TIMS) geochronological studies of baddeleyite have established that the age of gabbrodolerites of the dike is 1788 ± 4 Ma, corresponding to the final events of the Subbotka-Moshorin deformation stage (1788–1792 Ma).
