Tonalite vs Chalk

Tonalite 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 Tonalite and Chalk Reserves. Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture. 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.

Tonalite is available in black, brown, light to dark grey, white colors whereas, Chalk is available in grey, white, yellow colors. Appearance of Tonalite is Banded and Foilated and that of Chalk is Soft. Properties of rock is another aspect for Tonalite vs Chalk. The hardness of Tonalite is 6-7 and that of Chalk is 1. The types of Tonalite are Dacite whereas types of Chalk are Chalk Marl and Marl. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tonalite is bluish black while that of Chalk is white. The specific heat capacity of Tonalite is 0.92 kJ/Kg K 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.Tonalite is heat resistant, pressure resistant, water resistant whereas Chalk is heat resistant.
