4.8.6 Late Cenozoic Leucite Lamproites from the East
European Alpine Belt (Macedonia and Yugoslavia)
Altherr et al. (2004) described late Cenozooic leucite lamproites from the East
European Alpine belt of Macedonia and Yugoslavia. They described eight localities
of ultra potassic rocks within the Vardar suture zone and one locality in the
Southern Carpathian fold-and-thrust belt. Most of these volcanics are characterized
by high Mg# (66.6
