Products of alkaline basaltic volcanism extend from the Lu?enec Basin and Cerová Highland to the northern Hungary. Volcanic activity in this area has created a large number of volcanic forms. This paper describes apatite from heavy mineral assemblages recovered from volcanoclastic infillings of maars and diatremes. Euhedral to subhedral crystal fragments of apatite with variable colour represented approximately 2% of heavy mineral assemblages. A total of 27 apatite samples from Hodejov, Fi?akovo – Castle Hill and Jel?ovec maars, the Hajná?ka diatreme and from recently discovered maar structure near Gemerské Dechtáre village have been analysed using electron microprobe and Raman spectroscopy. Amount of substitution in diagrams Ca/100-Mn-Fe, S/100-P-Si and Fe-Ce-Mn sites correspond to the apatite from mafic magmatic rocks. A middle range of the Tetrahedral Substitution Index (TSI) between 0.63 and 7.56 is consistent with the apatites from alkaline magmatic rocks. These findings corroborate magmatic origin of apatite and its crystallization from alkaline basaltic parental magma.
