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.</p&gt;}, number={1}, journal={Natural Resources and Technology}, author={Boev, Ivan}, year={2022}, month={Jun.}, pages={35-45} }
