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 ...
It facilitates the aggregation of clay platelets which flocculate and stick together in a more stable aggregates structure. After the marine clay deposit is uplifted and is no longer exposed to salt water conditions, rainwater can slowly infiltrate the poorly compacted clay layer and the excess of NaCl present in seawater can also diffuse out ...
Quick clay is a unique type of marine clay indigenous to the glaciated terrains of Norway, North America, Northern Ireland, and Sweden. [24] It is a highly sensitive clay, prone to liquefaction , and has been involved in several deadly landslides .
Later, a rise in sea level, around 50 million years ago, caused widespread deposition, until 2 million years ago, of the London Clay across the County. The London Clay is a bluish-grey marine clay with isolated pockets of fossils especially where chalkier. The youngest part of the London Clay is known as the Claygate Beds and occurs widely in ...
The Oxford Clay (or Oxford Clay Formation) is a Jurassic marine sedimentary rock formation underlying much of southeast England, from as far west as Dorset and as far north as Yorkshire. The Oxford Clay Formation dates to the Jurassic, specifically, the Callovian and Oxfordian ages, [ 1 ] and comprises two main facies .
Hemipelagic sediment, or hemipelagite, is a type of marine sediment that consists of clay and silt-sized grains that are terrigenous and some biogenic material derived from the landmass nearest the deposits or from organisms living in the water.
These typically contain 35–65% clay and 65–35% carbonate. [2] [3] The term is today often used to describe indurated marine deposits and lacustrine (lake) sediments which more accurately should be named 'marlstone'. [4] Marlstone is an indurated (resists crumbling or powdering) rock of about the same composition as marl.
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 ...
