Abstract

The paper presents detailed petrographic research using optical microscopy on lamproite rocks around the village of Mrzen, Northern Macedonia. Detailed microscopic examinations of 5 specimens show that the rocks have typical porphyritic structures and in some places they also show sub-rounded textures with cavities filled with secondary calcite. Phenocrystals that have idiomorphic forms are represented by: olivine, clinopyroxene, orthopyroxene, plagioclase and magnetite. In some places there are changes - alterations in phenocrysts that are represented by: iddingsite, smectite-chlorite-goethite), clay and/or zeolites, and calcite. Microscopic examination shows that they are lamproites.
