Oolitic limestone texture
Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock. Marble forms when sedimentary limestone is heated and squeezed by natural rock-forming processes so that the grains recrystallize. If you look closely at a limestone, you can usually see fossil fragments (for example ...Oolitic limestones are a type of sedimentary rock that are primarily composed of calcium carbonate (CaCO3) and small, spherical grains known as ooids. Ooids are typically 0.25mm to 2mm in diameter and are formed from concentric layers of calcium carbonate that build up around a central nucleus, such as a shell fragment or a grain of sand.
