Petrographical photomicrographs of representative samples from Sung Valley ijolites in cross-polarized light. a Subhedral diopside, aegirine-augite, and nepheline forming the hypidiomorphic texture. b Subhedral to anhedral aegirine-augite showing simple twining along with the apatite and nepheline. c Aegirine-augite enclosed by nepheline with subhedral to anhedral titanite crystals forming the poikilitic texture. d Subhedral aegirine-augite, titanite, nepheline, and magnetite showing hypidiomorphic texture.
