#ThinSectionThursday A vision of volcanic loveliness 🌋 🥰 in this porphyritic phonolite from the Canary Islands. Big crystals of sodium-rich amphibole, Na-Fe clinopyroxene titanite, apatite, nepheline, and zircon, in a finer-grained groundmass mostly of sanidine feldspar. Field of view ca. 2mm wide. #Geology #IgneousPetrology #Microscopy
