Abstract

Glassy lava from Trlično is dacitic in composition and developed by incomplete mixing of two magmas of similar composition but different degree of groundmass crystallinity. By laminar lava flow banded texture developed consisting of bands with different magma types. Abundance of major and trace elements is within the variation range for dacites. Comparison with the Smrekovec andesites in Northern Slovenia indicates that the rocks do not originate from the same volcanic complex, displaced by tectonic activity.
