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