Silica speleothems take differenr forms such as cylindrical stems growing from either the floor or the ceiling in granitic caves. Mineralogically they are opal-A and accumulate in successive layers with a whiskery druse tip formed by gypsum crystals. Initially they are porous but progressively become infilled by opal precipitation. This results in formation of solid speleothems. their size is only a few millimetres long. Bacterial activity accelerate quartz dissolutio
