1 Definition

1.1 Definition

A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

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

1.3 Etymology

From a sediment left after the evaporation

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

5 Formation

5.1 Formation

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

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 Evaporite and Argillite Properties

Know all about Evaporite and Argillite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Argillite belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Argillite is Clastic, Polished. Evaporite appears Glassy, Vesicular and Foilated and Argillite appears Rough and Dull. The luster of Evaporite is subvitreous to dull while that of Argillite is waxy and dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Argillite is available in dark grey to black, pink, red, white colors. The commercial uses of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite and that of Argillite are fire resistant, used to manufracture paperweights and bookends.
