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
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture

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.
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Argillite vs Latite 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 Latite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Argillite and Properties of Latite. Learn more about Argillite vs Latite in the next section. The interior uses of Argillite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Latite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Argillite and Latite, 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 Latite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Argillite and Latite
Here you can know more about Argillite and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Argillite and Latite 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 Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Argillite vs Latite, 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, Latite is available in black, brown, green, grey, pink, white colors. Appearance of Argillite is Rough and Dull and that of Latite is Rough. Properties of rock is another aspect for Argillite vs Latite. The hardness of Argillite is 2-3 and that of Latite is 5-5.5. The types of Argillite are Metamorphic rock whereas types of Latite are Rhomb porphyries. 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 Latite is white. The specific heat capacity of Argillite is 0.87 kJ/Kg K and that of Latite is 0.92 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 Latite is heat resistant, pressure resistant.
