Abstract

The Tertiary intrusive rocks (30.5tO.5 m.y.) within the central part of the Vardar zone can be found in the Kratovo-Zletovo volcanic area. The area is situated between the margins of the Vardar zone and the Serbo-Macedonian massif. It has been the subject matter of investigation of many researchers (Rakicevic, Dumnurdzanov, Petkovski, 1976, Serafimovski, 1993). The geological base of the Vardar zone is made up of a series of Paleozoic rocks present as quartz-graphite schists and phyllites in which quartzites, quartz sandstones and chlorite-biotite schists alternate facially. The series is intruded by gabbros of Mesozoic age. The two earlier mentioned formations have been intruded by quartzmonzonite to quartzmonzonte porphyry intrusive Tertiary rocks. The youngest rocks are Miocene volcanic rocks of amphibolite andesite composition. Ouartzmonzo­nite and quartzmonzonite porphyry occur, as a smaller intrusive body with irregular shapes with slab like to irregular columnar rocks. They are grey, fairly hard with pronounced hypidiomorphic grain-like structure. Essentially, they are made up of intlmnediary zonar plagioclases and in some cases lamellar twinned, quartz, feldspars, biotite and plagioclase.
