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.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

More about Foidolite and Gabbro
Here you can know more about Foidolite and Gabbro. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Gabbro consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene and mineral content of Gabbro includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Foidolite vs Gabbro, 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, Gabbro is available in dark grey to black colors. Appearance of Foidolite is Dull and that of Gabbro is Veined and Shiny. Properties of rock is another aspect for Foidolite vs Gabbro. The hardness of Foidolite is 1.5 and that of Gabbro is 7. The types of Foidolite are Igneous rock whereas types of Gabbro are Anorthosite Gabbro and Norite Gabbro. 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 Gabbro is black. The specific heat capacity of Foidolite is 0.79 kJ/Kg K and that of Gabbro is 0.71 kJ/Kg K. 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 Gabbro is impact resistant, pressure resistant, wear resistant.
