Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate
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

Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
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.

Limestone vs Kenyte 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. Limestone vs Kenyte characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Kenyte. Learn more about Limestone vs Kenyte in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Kenyte include Decorative aggregates, Entryways, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Limestone and Kenyte, they have various applications in construction industry. The uses of Limestone in construction industry include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium and that of Kenyte 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.
More about Limestone and Kenyte
Here you can know more about Limestone and Kenyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Kenyte consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt 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 Limestone vs Kenyte, the texture, color and appearance plays an important role in determining the type of rock. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas, Kenyte is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Limestone is Rough and Banded and that of Kenyte is Banded and Foilated. Properties of rock is another aspect for Limestone vs Kenyte. The hardness of Limestone is 3-4 and that of Kenyte is 5.5-6. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Kenyte are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Limestone is white while that of Kenyte is white, greenish white or grey. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Kenyte is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Limestone is pressure resistant whereas Kenyte is heat resistant, impact resistant, wear resistant.
