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
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks

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.
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

More about Kenyte and Phyllite
Here you can know more about Kenyte and Phyllite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kenyte and Phyllite 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 Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Kenyte vs Phyllite, 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, Phyllite is available in black to grey, light greenish grey colors. Appearance of Kenyte is Banded and Foilated and that of Phyllite is Crinkled or Wavy. Properties of rock is another aspect for Kenyte vs Phyllite. The hardness of Kenyte is 5.5-6 and that of Phyllite is 1-2. The types of Kenyte are Foidolite whereas types of Phyllite are Phyllite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Kenyte and Phyllite is white, greenish white or grey. The specific heat capacity of Kenyte is 0.84 kJ/Kg K and that of Phyllite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Kenyte is heat resistant, impact resistant, wear resistant whereas Phyllite is heat resistant, pressure resistant, water resistant.
