1.1 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 yellow sandstone which is flexible when cut into thin strips

5.1 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.

Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
