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

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

More about Claystone and Kenyte
Here you can know more about Claystone and Kenyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Kenyte consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Kenyte includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Kenyte, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Kenyte is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Claystone is Rough and Dull and that of Kenyte is Banded and Foilated. Properties of rock is another aspect for Claystone vs Kenyte. The hardness of Claystone is 3.5-4 and that of Kenyte is 5.5-6. The types of Claystone are Claystone whereas types of Kenyte are Foidolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone is white while that of Kenyte is white, greenish white or grey. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Kenyte is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Kenyte is heat resistant, impact resistant, wear resistant.
