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
Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt

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.
Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

More about Kenyte and Siltstone
Here you can know more about Kenyte and Siltstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kenyte and Siltstone 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 Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Kenyte vs Siltstone, 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, Siltstone is available in brown, red, reddish brown colors. Appearance of Kenyte is Banded and Foilated and that of Siltstone is Rough. Properties of rock is another aspect for Kenyte vs Siltstone. The hardness of Kenyte is 5.5-6 and that of Siltstone is 6-7. The types of Kenyte are Foidolite whereas types of Siltstone are Siltstone. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Kenyte and Siltstone is white, greenish white or grey. The specific heat capacity of Kenyte is 0.84 kJ/Kg K and that of Siltstone 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.Kenyte is heat resistant, impact resistant, wear resistant whereas Siltstone is heat resistant, impact resistant, pressure resistant, water resistant.
