limestone is made underwater from the shells of animals. We know this because limestone also contains many fossils.
I think you are describing a type of limestone called coquina.
Any Type Of Limestone
Yes, limestone is a sedimentary rock primarily made up of calcite and aragonite minerals, which are derived from the shells of marine organisms. Over time, these shells accumulate and are compacted to form limestone rock.
Clastic sedimentary rocks.
== == Clastic sedimentary rocks.
Skeletal remains of many sea creatures settle on the ocean floor. Here they mix with sediments and eventually become sedimentary rock.
Yes, clam shells are made of calcium carbonate, which is a common mineral found in sedimentary rocks like limestone. Over time, these shells can become compressed and buried, eventually forming sedimentary rocks through the process of lithification.
Clastic sedimentary rocks are made of fragments from rocks, minerals, and shells. These fragments, called clasts, are compacted and cemented together over time to form rocks like sandstone, shale, and conglomerate.
Limestone made from shells would be an organic sedimentary rock.
