Members of the group are here recorded from five localities in Poland: a two-pyroxene andesite from the Kłodzko-Złoty Stok intrusion, a trachyandesite intrusion north of the Pieniny Mountains, a rapakivi-type granite from the Krasnopol intrusion, an anorthosite from the Suwałki Anorthosite Massif, and nepheline syenite from the Ełk syenite massif. Specific members found are chevkinite-(Ce), perrierite-(Ce) and, potentially, the Al-dominant analogue of perrierite-(Ce). The case is made that chevkinite-group minerals will, through systematic investigation, be found in a wide range of Polish igneous and metamorphic rocks.}, type={Article}, title={Chevkinite-group minerals in Poland}, URL={http://sd.czasopisma.pan.pl/Content/110353/PDF/5_Nejbert.pdf}, doi={10.24425/agp.2019.126451}, keywords={Chevkinite-group minerals, Chevkinite-(Ce), Perrierite-(Ce), Mineral chemistry, Petrological significance, Poland}, }
