Chalk: A biological limestone formed from shell debris

Chalk is a variety of limestone composed mainly of calcium carbonate derived from the shells of tiny marine animals known as foraminifera and from the calcareous remains of marine algae known as coccoliths. Chalk is usually white or light gray in color. It is extremely porous, permeable, soft and friable.

limestone Characteristics, Formation, Texture, Uses ...

Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone

GEO ExPro - Carbonate Geology of The Florida Keys

The younger oolitic Miami Limestone is composed of millions of ooids, formed in clear current-swept waters supersaturated with calcium and carbonate that precipitated out around a nucleus grain to form these tiny spherical pellets. Coring has shown that the oolite is underlain by the older coralline limestone.

Killer Climbs The Geology of Limestone Caves

As the crust slowly shifts, limestone fractures and cracks. Rainwater, which is naturally acidic, seeps into these fissures and slowly erodes away solid rock. The speed at which this erosion of limestone takes place varies greatly by: the volume and frequency of rain, the temperature, and variations in geology. Underground Rivers
