The first type, kamafugite, is plagioclasefree, consisted of Tirich phlogopite, melilite, leucite and nephelite. They have lower contents of SiO2 and Al2O3, but have high TiO2, CaO, MgO contents and K/Na and Mg# ratio whereas the second type, potassic trachybasalt, is abundant in plagioclase and contains no phlogopite, melilite, leucite and nephelite.
