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
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

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.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

Argillite vs Basanite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Argillite vs Basanite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Argillite and Properties of Basanite . Learn more about Argillite vs Basanite in the next section. The interior uses of Argillite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Basanite include Decorative aggregates and Homes. Due to some exceptional properties of Argillite and Basanite , they have various applications in construction industry. The uses of Argillite in construction industry include Used for flooring, stair treads, borders and window sills. and that of Basanite include Arrowheads, Construction aggregate, Cutting tool, Spear points.
More about Argillite and Basanite
Here you can know more about Argillite and Basanite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Argillite and Basanite consists of mineral content and compound content. The mineral content of Argillite includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase. You can also check out the list of all Sedimentary Rocks. When we have to compare Argillite vs Basanite , the texture, color and appearance plays an important role in determining the type of rock. Argillite is available in dark grey to black, pink, red, white colors whereas, Basanite is available in black, brown, green, grey, red, white colors. Appearance of Argillite is Rough and Dull and that of Basanite is Glassy or Pearly. Properties of rock is another aspect for Argillite vs Basanite . The hardness of Argillite is 2-3 and that of Basanite is 7. The types of Argillite are Not Available whereas types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Argillite is white to grey while that of Basanite is white. The specific heat capacity of Argillite is 0.87 kJ/Kg K and that of Basanite is 0.74 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Argillite is heat resistant, impact resistant whereas Basanite is heat resistant, impact resistant, pressure resistant, wear resistant.
