Marine clay is a type of clay found in coastal regions around the world. In the northern, deglaciated regions, it can sometimes be quick clay , which is notorious for being involved in landslides. Marine clay is a particle of soil that is dedicated to a particle size class, this is usually associated with USDA's classification with sand at 0 ...
Quick clay, also known as Leda clay and Champlain Sea clay in Canada, is any of several distinctively sensitive glaciomarine clays found in Canada, Norway, Russia, Sweden, Finland, the United States, and other locations around the world.
The clay has been used in several locations for making bricks, notably near Dunton Green and Wye in Kent. Gault often contains numerous phosphatic nodules, some thought to be coprolites, and may also contain sand as well as small grains of the mineral glauconite. Crystals of the mineral selenite are fairly common in places, as are nodules of ...
Bay muds often have a high organic content, consisting of decayed organisms at lower depths, but may also contain living creatures when they occur at the upper soil layer and become exposed by low tides; then, they are called mudflats, an important ecological zone for shorebirds and many types of marine organisms. Great attention was not given ...
The Kimmeridge Clay is a sedimentary deposit of fossiliferous marine clay which is of Late Jurassic to lowermost Cretaceous age and occurs in southern and eastern England and in the North Sea. [1] This rock formation is the major source rock for North Sea oil .
The bulk of red clay consists of eolian dust. Accessory constituents found in red clay include meteorite dust, fish bones and teeth, whale ear bones, and manganese micro-nodules. [2] These pelagic sediments are typically bright red to chocolate brown in color. The color results from coatings of iron oxide and manganese oxide on the sediment ...
The Veldhoven Formation has a shallow marine (less than 200 meters deep) or beach facies. It consists of an alternation of glauconiferous and micaceous fine sands and micaceous clays. In some places hardgrounds or shell-rich layers occur. The formation is Chattian, 28.4 to 23.0 million years old.
The Hannut Formation (French: Formation de Hannut; Dutch: Formatie van Hannut; abbreviation: Hn) is a geologic formation in the subsurface of northern Belgium.The formation consists of marine clay and silt, alternating with more sandy layers.
