Schist vs Tonalite

Schist vs Tonalite 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 Schist and Tonalite Reserves. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture. 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 Schist vs Tonalite information and Schist vs Tonalite characteristics in the upcoming sections.

Schist vs Tonalite 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. Schist vs Tonalite characteristics assist us to distinguish and recognize rocks.

Schist is available in black, blue, brown, dark brown, green, grey, silver colors whereas, Tonalite is available in black, brown, light to dark grey, white colors. Appearance of Schist is Layered and Shiny and that of Tonalite is Banded and Foilated. Properties of rock is another aspect for Schist vs Tonalite. The hardness of Schist is 3.5-4 and that of Tonalite is 6-7. The types of Schist are Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist. whereas types of Tonalite are Dacite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Schist is white while that of Tonalite is bluish black. The specific heat capacity of Schist is 0.70 kJ/Kg K and that of Tonalite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Schist is impact resistant, pressure resistant, water resistant whereas Tonalite is heat resistant, pressure resistant, water resistant.
