Lavarosette
A lavarosette (also lava rose or lava flower) is a formation of volcanic rock with radially arranged lava columns . The alignment of the lava columns is always perpendicular to the cooling surface, i.e. the outer surface of a lava tunnel or an intrusion .
Often these formations are also called basalt rosette, basalt rose or basalt flower, even if they are not made of basalt.
