stalagmite in Science


  1. A cylindrical or conical mineral deposit, similar to a stalactite but built up from the floor of a cave or cavern. Stalagmites are typically broader than stalactites. The two formations are often, but not always, paired, and they sometimes join at a midpoint to form a pillar. Compare stalactite.
