Definition
Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar
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 French mine ore, mine + ette
From Latin Argilla (clay) and -ite in English which became agrilla+ -ite = Argillite

Formation
Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
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.

More about Minette and Argillite
Here you can know more about Minette and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Minette and Argillite consists of mineral content and compound content. The mineral content of Minette includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Argillite includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Minette vs Argillite, the texture, color and appearance plays an important role in determining the type of rock. Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Minette is Dull, Banded and Foilated and that of Argillite is Rough and Dull. Properties of rock is another aspect for Minette vs Argillite. The hardness of Minette is 5-6 and that of Argillite is 2-3. The types of Minette are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Argillite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Minette is white while that of Argillite is white to grey.
