Lamination (geology)

Lamina ( from Latin lamina = plate, disc, plural: laminae ) is a feature in the geology of sedimentary layers built structures. The term describes the smallest unit - a single bright or dark situation - a Laminits. A Laminit is deposited in thin layers of sediment, the name refers to the defining structural feature. An example of this form of disposal is varves.

As laminae individual layers are defined, which have a thickness of less than 1 cm, but usually significantly thinner ( thickness of less than 0.1 mm to 1 mm are common symptoms). The Laminationstypen after their formation ( clastic, evaporitic and Organogen ) are variants of this photomicrograph. Together you is the fine-grained sediment.

Laminite result in stagnant or slow-flowing waters - the flow in parallel flow bands ( equidistant paths ) is called " laminar flow " - but can also be found in certain phases form when lava flows and mud flows.

A sequence of rock is constructed in this manner, it is referred to as " laminated ". " Lamination " or " laminated " are designations for the process that results in the formation of a Laminits. Under Warve dedicated to providing educational way further explanation.
