Definition
Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone

Formation
Ijolite 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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Ijolite and Metapelite
Here you can know more about Ijolite and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ijolite and Metapelite consists of mineral content and compound content. The mineral content of Ijolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Ijolite vs Metapelite, the texture, color and appearance plays an important role in determining the type of rock. Ijolite is available in brown, buff, cream, green, grey, pink, white colors whereas, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Ijolite is Banded and Foilated and that of Metapelite is Banded. Properties of rock is another aspect for Ijolite vs Metapelite. The hardness of Ijolite is 5.5-6 and that of Metapelite is 5-6. The types of Ijolite are Not Available whereas types of Metapelite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ijolite is white while that of Metapelite is unknown. The specific heat capacity of Ijolite is Not Available and that of Metapelite is 0.72 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Ijolite is heat resistant, impact resistant, wear resistant whereas Metapelite is heat resistant, impact resistant, pressure resistant.
