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
Aplite is a fine-grained granite composed mainly of feldspar and quartz

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.
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

Kenyte vs Aplite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Kenyte vs Aplite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Kenyte and Properties of Aplite. Learn more about Kenyte vs Aplite in the next section. The interior uses of Kenyte include Decorative aggregates, Entryways, Homes, Interior decoration and Kitchens whereas the interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Kenyte and Aplite, they have various applications in construction industry. The uses of Kenyte in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics and that of Aplite include As dimension stone.
More about Kenyte and Aplite
Here you can know more about Kenyte and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kenyte and Aplite 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 Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Kenyte vs Aplite, 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, Aplite is available in black, grey, orange, pink, white colors. Appearance of Kenyte is Banded and Foilated and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Kenyte vs Aplite. The hardness of Kenyte is 5.5-6 and that of Aplite is 6.5. The types of Kenyte are Foidolite whereas types of Aplite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Kenyte and Aplite is white, greenish white or grey. The specific heat capacity of Kenyte is 0.84 kJ/Kg K and that of Aplite 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 Aplite is heat resistant, wear resistant.
