The Triassic metabasalts of Dudin Krš, near Kosovska Mitrovica, Serbia

Abstract

This paper presents the geochemical characteristics of the metabasalts of Dudin Krš, near Kosovska Mitrovica. The Dudin Krš is the easternmost occurrence of Middle Triassic rift-related volcanic rocks in the Dinarides. Generally, these rocks show similarities to other Triassic volcanic rocks of the Dinarides. They are high-magnesian, ol and ne-normative basalts, with low Zr/Nb and medium/low Ti/Zr and Ti/Y ratios. They exhibit transitional geochemical characteristics, between E-MORB and subalkaline basalts of continental rift zones. Their presence and geochemical affinity is evidence of rifting processes along the continental slope of the Adria block during Middle Triassic.
