What is the meaning of argillite?

Definition of argillite. : a compact argillaceous rock cemented by silica and having no slaty cleavage.

What is another name for poorly lithified argillites?

Another name for poorly lithified argillites is mudstone. These rocks, although variable in composition, are typically high in aluminium and silica with variable alkali and alkaline earth cations. The term pelitic or pelite is often applied to these sediments and rocks.

What is the difference between argillite and shale?

Argillite (/ ˈ ɑːr dʒ ɪ l aɪ t /) is a fine-grained sedimentary rock composed predominantly of indurated clay particles. Argillaceous rocks are basically lithified muds and oozes. They contain variable amounts of silt-sized particles. The argillites grade into shale when the fissile layering typical of shale is developed.

What are the characteristics of argillaceous rocks?

Argillaceous rocks are basically lithified muds and oozes. They contain variable amounts of silt -sized particles. The argillites grade into shale when the fissile layering typical of shale is developed. Another name for poorly lithified argillites is mudstone. These rocks, although variable in composition,...

What type of rock is argillite?

A highly compacted sedimentary or slightly metamorphic rock consisting primarily of particles of clay or silt. Argillite differs from mudstone in that it does not have the same fine laminations, and from shale and slate in that it is not fissile.

What is the composition of poorly lithified argillites?

They contain variable amounts of silt -sized particles. The argillites grade into shale when the fissile layering typical of shale is developed. Another name for poorly lithified argillites is mudstone. These rocks, although variable in composition, are typically high in aluminium and silica with variable alkali and alkaline earth cations.

What is the meaning of argil?

A metamorphic rock, intermediate between shale and slate, that does not possess true slaty cleavage. [Latin argilla, argil; see argil + -ite .] American Heritage® Dictionary of the English Language, Fifth Edition.
