Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash. Clastic Sedimentary Rocks:Similarly, limestone can be formed through the accumulation and compression of organic matter such as shells and plant debris. Overall, the formation of limestone is a gradual process that occurs over geologic time scales, involving the accumulation, compaction, and lithification of calcium carbonate-rich materials in marine environments.٢٥ جمادى الأولى ١٤٤٤ هـ ...

Along the way, it picks up carbon dioxide, from the air and from any organic matter it passes as it dribbles down ...
Carboniferous Limestone is a hard sedimentary rock made largely of calcium carbonate. It is generally light-grey in colour. It was formed in warm, shallow tropical seas teeming with life.

Limestone may form inorganically or by biochemical processes. There are many types of limestone because of the variety of conditions under which it is produced.Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.
