21.5" Calcite & Aragonite Stalactite Formation
This enormous formation of calcite coating aragonite comes from Ighoud, Morocco. This large mass of mineral was removed from a cave where stalactite formations from iron-rich matrix are enshrouded in layers of aragonite and calcite crystal. About a third of this specimen has a web-like structure, while the rest is covered in a mass of aragonite crystal cluster.
Stalactites form when water, seeping through rock, reaches an opening such as a cave or tunnel. Once this mineral-rich water (calcite in this case) precipitates out of the rock wall/ceiling, it leaves behind a crystal as the precipitate builds with each drop of water.
Stalagmites are likely to form from this process as those drops land on a cave floor, since the drops from the ceiling will still contain high mineral content. As long as water keeps flowing, it will continue to precipitate into stalactites and stalagmites.
