Rimstonenoun

A secondary mineral deposit, with a stone-wall-like appearance made up of calcite and other minerals, that builds up to create cave pools.

Rimstone

Rimstone, also called gours, is a type of speleothem (cave formation) in the form of a stone dam. Rimstone is made up of calcite and other minerals that build up in cave pools.

Flowstonenoun

(geology) A secondary layered mineral deposit of calcite or other mineral, formed by water flowing down the walls and along the floor of a cave.

Flowstone

Flowstones are composed of sheetlike deposits of calcite or other carbonate minerals, formed where water flows down the walls or along the floors of a cave. They are typically found in , in limestone, where they are the most common speleothem.
