Frostwork (geology)

In geology, frostwork is a type of speleothem with acicular ("needle-like") growths almost always composed of aragonite (a polymorph of calcite) or calcite replaced aragonite. It is a variety of anthodite. Frostwork can also be made of opal or gypsum. In some caves frostwork may grow on top of cave popcorn or boxwork.
