Turbidite and Argillite
Definition
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

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.

All about Turbidite and Argillite Properties
Know all about Turbidite and Argillite properties here. All properties of rocks are important as they define the type of rock and its application. Turbidite and Argillite belong to Sedimentary Rocks.Texture of Turbidite is Mud-rich, Sandy whereas that of Argillite is Clastic, Polished. Turbidite appears Dull and Banded and Argillite appears Rough and Dull. The luster of Turbidite is metallic while that of Argillite is waxy and dull. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas Argillite is available in dark grey to black, pink, red, white colors. The commercial uses of Turbidite are cemetery markers, creating artwork and that of Argillite are fire resistant, used to manufracture paperweights and bookends.
