A sedimentary rock composed of calcium carbonate; includes many varieties. (See oolitic limestone; dolomitic limestone; crystalline limestone).

A stone beam or horizontal member spanning the top of an opening, such as a doorway or window, and supporting the wall above it.
A condition when one edge of a stone is higher than the adjacent edge.
|Lug Sill|| |
