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
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

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.
Tachylite 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 Tachylite
Here you can know more about Kenyte and Tachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kenyte and Tachylite 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 Tachylite includes Feldspar, Olivine. You can also check out the list of all Igneous Rocks. When we have to compare Kenyte vs Tachylite, 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, Tachylite is available in black, dark brown colors. Appearance of Kenyte is Banded and Foilated and that of Tachylite is Glassy. Properties of rock is another aspect for Kenyte vs Tachylite. The hardness of Kenyte is 5.5-6 and that of Tachylite is 5.5. The types of Kenyte are Not Available whereas types of Tachylite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Kenyte is white, greenish white or grey while that of Tachylite is vermilion.
