Marine sedimentation of nano-quartz forming …
A new theory for formation of flint in the North Sea Danian Ekofisk Formation chalk has been formulated, according to which the flint formed by sedimentation of nano-size α-quartz particles. These α-quartz particles have crystallized in the sea from silicon supplied from dissolution of radiolarians. In the present work this model has been tested by sedimentological and mineralogical investigation of sedimentary features in chalk …
Chalk: A biological limestone formed from shell …
Chalk forms from a fine-grained marine sediment known as ooze. When foraminifera, marine algae, or other organisms living on the bottom or in the waters above die, their remains sink to the bottom and accumulate as ooze. If most of the accumulating organic debris consists of calcium carbonate, then chalk will be the type of

Chalk - Wikipedia
18.03.2002 · Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite. Calcite is an ionic salt called calcium carbonate or CaCO 3. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite shells shed from micro-organisms called coccolithophores.
Marines Sediment – Wikipedia
Als marine Sedimente oder Meeressedimente bezeichnet die Geologie jene Sedimente, die sich in Meeresbecken ablagern bzw. abgelagert haben. Sie stellen weltweit den größten Anteil unter sowohl den rezenten Sedimenten als auch den Sedimentgesteinen. Die Masse unter den Meeressedimenten stellen wiederum die Schelfsedimente. Den Meeressedimenten gegenüber stehen die terrestrischen Sedimente die alle Ablagerungen des Festlands, einschließlich der Süßgewässer, umfassen. Marine ...
Pelagic sediment - Wikipedia
29.01.2006 · Pelagic sediment or pelagite is a fine-grained sediment that accumulates as the result of the settling of particles to the floor of the open ocean, far from land. These particles consist primarily of either the microscopic, calcareous or siliceous shells of phytoplankton or zooplankton; clay-size siliciclastic sediment; or some mixture of these.
