Limestones containing between 25 and 50 percent clay particles are called marls. There are also transitional formations between limestones and sandstones. Natural chalk is also a limestone, consisting of 96–99 percent CaCO 3. The metamorphism of limestone leads to the formation of marble. Transitional varieties are called marmorate limestones.

Limestone - Wikipedia

Coastal limestones are often eroded by organisms which bore into the rock by various means. This process is known as bioerosion. It is most common in the tropics, and it is known throughout the fossil record (see Taylor and Wilson, 2003). Bands of limestone emerge from the Earth's surface in often spectacular rocky outcrops and islands.
