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
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

More about Kenyte and Marble
Here you can know more about Kenyte and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kenyte and Marble 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 Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Kenyte vs Marble, 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, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Kenyte is Banded and Foilated and that of Marble is Veined and Shiny. Properties of rock is another aspect for Kenyte vs Marble. The hardness of Kenyte is 5.5-6 and that of Marble is 3-4. The types of Kenyte are Foidolite whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Kenyte and Marble is white, greenish white or grey. The specific heat capacity of Kenyte is 0.84 kJ/Kg K and that of Marble is 0.88 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 Marble is heat resistant.
