How Stalactites and Stalagmites Form

 · The speleothems with which most people are familiar are stalactites and stalagmites. Stalactites grow down from the cave ceiling, while stalagmites grow up from the cave floor. It''s easy to remember which is which: Stalactites have a "T" for top and stalagmites have a "G" for ground. Speleothems actually form because of water.

Calcite

Calcite - Calcite - Origin and occurrence: A large percentage of the calcite in rocks was deposited in sedimentary environments; consequently, calcite is a constituent of several diverse sediments, sedimentary rocks, and their metamorphosed products. A minor amount of the Earth''s calcite is of magmatic (i.e., igneous) origin; it is the chief constituent of the rare rock called carbonatite.

Calcite

Calcite is an insulator with a band gap of around 6 eV and crystallizes in a trigonal system with R 3 c symmetry. The primitive unit cell is a rhombohedron, which is also referred to as the "structural unit cell.". Using the rhombohedral axes of the structural unit cell, the most stable cleavage plane is the (211) plane.
