Chalk vs Phonolite

Chalk vs Phonolite 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 Chalk and Phonolite Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic. 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 Chalk vs Phonolite information and Chalk vs Phonolite characteristics in the upcoming sections.

Chalk vs Phonolite 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. Chalk vs Phonolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Phonolite. Learn more about Chalk vs Phonolite in the next section. The interior uses of Chalk include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Chalk and Phonolite, they have various applications in construction industry. The uses of Chalk in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for manufacture of quicklime and slaked lime, Source of calcium and that of Phonolite 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.

Chalk is available in grey, white, yellow colors whereas, Phonolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Chalk is Soft and that of Phonolite is Banded and Foilated. Properties of rock is another aspect for Chalk vs Phonolite. The hardness of Chalk is 1 and that of Phonolite is 5.5-6. The types of Chalk are Not Available whereas types of Phonolite are Kenyte. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk and Phonolite is white. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Phonolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Chalk is heat resistant whereas Phonolite is heat resistant, impact resistant, wear resistant.
