Definition

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

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

Etymology

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

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

Formation

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.

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.
