Definition
Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Origin

Etymology
From the first syllable of the Finnish words Ii-vaara, Iijoki, &c. commonly used geographical names in Finland, and the Gr. Xiflos, a stone
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

More about Ijolite and Turbidite
Here you can know more about Ijolite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ijolite and Turbidite 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 Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Ijolite vs Turbidite, 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, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Ijolite is Banded and Foilated and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Ijolite vs Turbidite. The hardness of Ijolite is 5.5-6 and that of Turbidite is 3. The types of Ijolite are Not Available whereas types of Turbidite 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 Turbidite is white, greenish white or grey. The specific heat capacity of Ijolite is Not Available and that of Turbidite is 0.92 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 Turbidite is heat resistant.
