Shale vs Slate

Shale vs Slate 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 Shale and Slate Reserves. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. 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. 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 Shale vs Slate information and Shale vs Slate characteristics in the upcoming sections.

Shale vs Slate 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. Shale vs Slate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shale and Properties of Slate. Learn more about Shale vs Slate in the next section.

Shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue colors. Appearance of Shale is Muddy and that of Slate is Dull. Properties of rock is another aspect for Shale vs Slate. The hardness of Shale is 3 and that of Slate is 3-4. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale whereas types of Slate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shale is white while that of Slate is light to dark brown. The specific heat capacity of Shale is 0.39 kJ/Kg K and that of Slate is 0.76 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Shale is heat resistant, impact resistant whereas Slate is heat resistant, impact resistant, pressure resistant, wear resistant.
