Slate vs Granite

Slate vs Granite 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 Slate and Granite Reserves. Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone. 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 Slate vs Granite information and Slate vs Granite characteristics in the upcoming sections.

Slate vs Granite 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. Slate vs Granite characteristics assist us to distinguish and recognize rocks.

Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue colors whereas, Granite is available in black, grey, orange, pink, white colors. Appearance of Slate is Dull and that of Granite is Veined or Pebbled. Properties of rock is another aspect for Slate vs Granite. The hardness of Slate is 3-4 and that of Granite is 6-7. The types of Slate are Phyllite, Schist, and Slate whereas types of Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite, Hybrid Granite, Granodiorite and Alkali Feldspar Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Slate is light to dark brown while that of Granite is white. The specific heat capacity of Slate is 0.76 kJ/Kg K and that of Granite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Slate is heat resistant, impact resistant, pressure resistant, wear resistant whereas Granite is heat resistant, wear resistant.
