Marine clay
Encyclopedia
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.
Clay particles can self-assemble into various configurations, each with totally different properties.

, the excess ions allow a loose, open structure that is open to water infiltration. Once stranded and dried by ancient, changing ocean levels, it becomes a geotechnical engineering

During the construction of Marina Barrage in Singapore, marine clay was found at the site. Since marine clay was the cause of Nicoll Highway's collapse years ago, the construction team had to remove all the marine clay to ensure the stability of Marina Barrage. Later on, they found marine clay mixed with seawater even in the deeper underground.
Clay
Clay is a general term including many combinations of one or more clay minerals with traces of metal oxides and organic matter. Geologic clay deposits are mostly composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure.- Formation :Clay minerals...

Quick clay
Quick clay, also known as Leda clay and Champlain Sea clay in Canada, is a unique form of highly sensitive marine clay, with the tendency to change from a relatively stiff condition to a liquid mass when it is disturbed. Undisturbed quick clay resembles a water-saturated gel...

When clay is deposited in the ocean
Ocean
An ocean is a major body of saline water, and a principal component of the hydrosphere. Approximately 71% of the Earth's surface is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas.More than half of this area is over 3,000...

Geotechnical engineering
Geotechnical engineering is the branch of civil engineering concerned with the engineering behavior of earth materials. Geotechnical engineering is important in civil engineering, but is also used by military, mining, petroleum, or any other engineering concerned with construction on or in the ground...

Geologic hazards
A geologic hazard is one of several types of adverse geologic conditions capable of causing damage or loss of property and life. These hazards consist of sudden phenomena and slow phenomena:Sudden phenomena include:...
