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
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface
Discoverer

Unknown
Etymology
From the mountain ranges- Mount Kenya and is named by J. W. Gregory in 1900
From its mineral and compound content and its relation with Basalt and Andesite rock

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.
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

More about Kenyte and Basaltic Trachyandesite
Here you can know more about Kenyte and Basaltic Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kenyte and Basaltic Trachyandesite 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 Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Kenyte vs Basaltic Trachyandesite, 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, Basaltic Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Kenyte is Banded and Foilated and that of Basaltic Trachyandesite is Dull and Soft. Properties of rock is another aspect for Kenyte vs Basaltic Trachyandesite. The hardness of Kenyte is 5.5-6 and that of Basaltic Trachyandesite is 6. The types of Kenyte are Foidolite whereas types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface.
