The Sm-Nd isotope system has been used for dating of micaschist and pegmatite garnets from the southeastern part of the Veporic unit in the Western Carpathians. The purpose of this study was to determine the timing of peak metamorphic conditions in the micaschists and the age of magmatic crystallization of pegmatite, because of relatively high closure temperature for the Sm-Nd system in garnet.

Samples

Two representative samples have been investigated. The garnet-bearing micasch...
