Formation

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

Claystone vs Amphibolite 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 Claystone and Amphibolite Reserves. Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. 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 Claystone vs Amphibolite information and Claystone vs Amphibolite characteristics in the upcoming sections.

More about Claystone and Amphibolite

Here you can know more about Claystone and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Amphibolite consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Amphibolite, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Amphibolite is available in black, brown, green, grey colors. Appearance of Claystone is Rough and Dull and that of Amphibolite is Foliated. Properties of rock is another aspect for Claystone vs Amphibolite. The hardness of Claystone is 3.5-4 and that of Amphibolite is 6-7. The types of Claystone are Claystone whereas types of Amphibolite are Hornblendite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone is white while that of Amphibolite is white to grey. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Amphibolite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Amphibolite is heat resistant, pressure resistant, wear resistant.
