Calcite (Inventory)/Coral Pipes
From LagWiki
Coral Pipes, also known as "calcified silt pillars", are clusters of vertically oriented speleothems that form by calcite encrusting mud, silt interior.
Coral pipes form in clusters only a few centimeters apart. Each tower-like formation is usually less than 10 cm in height. Coral pipes are taller than they are wide. In cross section, they are concentric layers of calcite (or other mineral) over a soft silt or mud internal core. Coral pipes form on steeply sloping floors or walls.
