Scoria vs Foidolite


Definition

Definition
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%

Formation

Formation
Foidolites 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.   
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

Foidolite vs Scoria 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 Foidolite and Scoria Reserves. Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. 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 Foidolite vs Scoria information and Foidolite vs Scoria characteristics in the upcoming sections.

More about Foidolite and Scoria

Here you can know more about Foidolite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Scoria consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene and mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Foidolite vs Scoria, the texture, color and appearance plays an important role in determining the type of rock. Foidolite is available in black, brown, colourless, green, grey, pink, white colors whereas, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Foidolite is Dull and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Foidolite vs Scoria. The hardness of Foidolite is 1.5 and that of Scoria is 5-6. The types of Foidolite are Not Available whereas types of Scoria are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Foidolite and Scoria is white. The specific heat capacity of Foidolite is Not Available and that of Scoria is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Foidolite is heat resistant, wear resistant whereas Scoria is heat resistant, impact resistant, pressure resistant, wear resistant.
