Marl Scala dei Turchi coastal marl formation, southern Sicily. Marl is an earthy material rich in carbonate minerals, clays, and silt.When hardened into rock, this becomes marlstone.It is formed in marine or freshwater environments, often through the activities of algae.. Marl makes up the lower part of the cliffs of Dover, and the Channel Tunnel follows these marl …A stalactite (from the Greek stalasso, "to drip", and meaning "that which drips") is a type of formation that hangs from the ceiling of caves, hot springs, or manmade structures such as bridges and mines. Any material which is soluble, can be deposited as a colloid, or is in suspension, or is capable of being melted, may form a stalactite. Karst is an area of land made up of limestone. Limestone, also known as chalk or calcium carbonate, is a soft rock that dissolves in water. As rainwater seeps into the rock, it slowly erodes. Karst landscapes can be worn away from the top or dissolved from a weak point inside the rock. Karst landscapes feature caves, underground streams and ...

Formation of the sandstones are cemented grains that may either be fragments of a pre-existing rock or be mono-minerallic crystals. The cements binding these grains together are typically calcite, clays, and silica. Grain sizes in sands are defined (in geology) within the range of 0.0625 mm to 2 mm (0.0025–0.08 inches).
