1.1 Definition

Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

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

5.1 Formation

Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

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.

Laterite vs Argillite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Laterite and Argillite Reserves. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. 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. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Laterite vs Argillite information and Laterite vs Argillite characteristics in the upcoming sections.

More about Laterite and Argillite

Here you can know more about Laterite and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Argillite consists of mineral content and compound content. The mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, 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 Sedimentary Rocks. When we have to compare Laterite vs Argillite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Laterite is Rough and Banded and that of Argillite is Rough and Dull. Properties of rock is another aspect for Laterite vs Argillite. The hardness of Laterite is 2 and that of Argillite is 2-3. The types of Laterite are Not Available 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 Laterite is white while that of Argillite is white to grey.
