Cave flags get their name because they are shaped like a flag composed of sediments in a karst cave. When a rock protrudes from the top or wall of a cave, water flows along the sloping rock surface and releases calcium carbonate. If this deposit is wide enough, it will form a cave flag. A cave flag’s width may reach 1 m, and the thickness is between 2.5 mm and 10 mm. Cave flags can be transparent or translucent and generate excellent percussion sounds. Stripes of different colours can form when the seeping water contains various impurities (Fig. 14).
