Definition
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%
Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent

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.
Teschenite 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.

More about Foidolite and Teschenite
Here you can know more about Foidolite and Teschenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Teschenite consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene and mineral content of Teschenite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Foidolite vs Teschenite, the texture, color and appearance plays an important role in determining the type of rock. Foidolite is available in black, brown, green, grey, pink, white colors whereas, Teschenite is available in dark grey to black colors. Appearance of Foidolite is Dull and that of Teschenite is Veined and Shiny. Properties of rock is another aspect for Foidolite vs Teschenite. The hardness of Foidolite is 1.5 and that of Teschenite is 7. The types of Foidolite are Not Available whereas types of Teschenite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Foidolite is white while that of Teschenite is black. The specific heat capacity of Foidolite is Not Available and that of Teschenite 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 Teschenite is impact resistant, pressure resistant, wear resistant.
