Phonolite vs Chalk

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

Phonolite vs Chalk 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 Chalk characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Phonolite and Properties of Chalk. Learn more about Phonolite vs Chalk in the next section. The interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Chalk include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Phonolite and Chalk, 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 Chalk 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.

Phonolite is available in brown, buff, cream, green, grey, pink, white colors whereas, Chalk is available in grey, white, yellow colors. Appearance of Phonolite is Banded and Foilated and that of Chalk is Soft. Properties of rock is another aspect for Phonolite vs Chalk. The hardness of Phonolite is 5.5-6 and that of Chalk is 1. The types of Phonolite are Kenyte whereas types of Chalk are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Phonolite and Chalk is white. The specific heat capacity of Phonolite is Not Available and that of Chalk is 0.90 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 Chalk is heat resistant.
