Definition

A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles

Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate

Etymology

From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

From Latin Argilla (clay) and -ite in English which became agrilla+ -ite = Argillite

Formation

Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

An argillite is a fine-grained sedimentary rock mainly composed of clay particles which forms from lithified muds which contain variable amounts of silt-sized particles.
