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
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

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.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

More about Kenyte and Claystone
Here you can know more about Kenyte and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kenyte and Claystone 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 Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Kenyte vs Claystone, 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, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Kenyte is Banded and Foilated and that of Claystone is Rough and Dull. Properties of rock is another aspect for Kenyte vs Claystone. The hardness of Kenyte is 5.5-6 and that of Claystone is 3.5-4. The types of Kenyte are Foidolite whereas types of Claystone are Claystone. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Kenyte and Claystone is white, greenish white or grey. The specific heat capacity of Kenyte is 0.84 kJ/Kg K and that of Claystone 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.Kenyte is heat resistant, impact resistant, wear resistant whereas Claystone is heat resistant, impact resistant.
