Definition

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
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

Formation

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.
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

Kenyte vs Adakite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Kenyte and Adakite Reserves. 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. Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Kenyte vs Adakite information and Kenyte vs Adakite characteristics in the upcoming sections.

Kenyte vs Adakite 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 Adakite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Kenyte and Properties of Adakite. Learn more about Kenyte vs Adakite in the next section. The interior uses of Kenyte include Decorative aggregates, Entryways, Homes, Interior decoration and Kitchens whereas the interior uses of Adakite include Decorative aggregates, Floor tiles, Homes, Hotels and Kitchens. Due to some exceptional properties of Kenyte and Adakite, 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 Adakite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.

More about Kenyte and Adakite

Here you can know more about Kenyte and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kenyte and Adakite 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 Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Kenyte vs Adakite, 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, Adakite is available in black, brown, light to dark grey colors. Appearance of Kenyte is Banded and Foilated and that of Adakite is Dull and Soft. Properties of rock is another aspect for Kenyte vs Adakite. The hardness of Kenyte is 5.5-6 and that of Adakite is 3-4. The types of Kenyte are Foidolite whereas types of Adakite are Intermediate volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Kenyte is white, greenish white or grey while that of Adakite is bluish black. The specific heat capacity of Kenyte is 0.84 kJ/Kg K and that of Adakite 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 Adakite is heat resistant, pressure resistant, wear resistant.
