Definition
Kenyte is a variety of porphyritic phonolite or trachyte rock with rhomb shaped phenocrysts of anorthoclase with variable olivine and augite in a glassy matrix
Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite
Origin

Etymology
From the mountain ranges- Mount Kenya and is named by J. W. Gregory in 1900
From the first syllable of the Finnish words Ii-vaara, Iijoki, &c. commonly used geographical names in Finland, and the Gr. Xiflos, a stone

Archaeological Significance
Formation
Kenyte 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.
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.

More about Kenyte and Ijolite
Here you can know more about Kenyte and Ijolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kenyte and Ijolite consists of mineral content and compound content. The mineral content of Kenyte includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite and mineral content of Ijolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Kenyte vs Ijolite, the texture, color and appearance plays an important role in determining the type of rock. Kenyte is available in brown, buff, cream, green, grey, pink, white colors whereas, Ijolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Kenyte is Banded and Foilated and that of Ijolite is Banded and Foilated. Properties of rock is another aspect for Kenyte vs Ijolite. Hardness of Kenyte and Ijolite is 5.5-6. The types of Kenyte are Foidolite whereas types of Ijolite are Alkaline rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface.
