1 Definition

1.1 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

Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava

5.1 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.

Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

Argillite vs Andesite 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 Argillite and Andesite Reserves. 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. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. 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.

More about Argillite and Andesite

Here you can know more about Argillite and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Argillite and Andesite 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 Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Argillite vs Andesite, 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, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Argillite is Rough and Dull and that of Andesite is Dull and Soft. Properties of rock is another aspect for Argillite vs Andesite. The hardness of Argillite is 2-3 and that of Andesite is 7. The types of Argillite are Not Available whereas types of Andesite are Icelandite. 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 Andesite is white. The specific heat capacity of Argillite is 0.87 kJ/Kg K and that of Andesite is 2.39 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 Andesite is heat resistant, pressure resistant, wear resistant.
