Provenance study of detrital garnets and rutiles from basaltic pyroclastic rocks of Southern Slovakia (Western Carpathians)

Autor: Nemec Ondrej, Huraiová Monika

Publikováno v: Geologica Carpathica, Vol 69, Iss 1, Pp 17-29 (2018)

Detrital garnets and rutiles have been recovered from basaltic pyroclastic rocks in the northern part of the Pannonian Basin and characterized using electron probe microanalysis and imaging. All garnets are dominated by the almandine component, excep
