Shale vs Pegmatite

Shale vs Pegmatite 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 Pegmatite Reserves. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals. 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 Pegmatite information and Shale vs Pegmatite characteristics in the upcoming sections.

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

Shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors. Appearance of Shale is Muddy and that of Pegmatite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Shale vs Pegmatite. The hardness of Shale is 3 and that of Pegmatite is 7. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale whereas types of Pegmatite are Granite Pegmatite, Gabbro Pegmatite and Diorite Pegmatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shale and Pegmatite is white. The specific heat capacity of Shale is 0.39 kJ/Kg K and that of Pegmatite 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.Shale is heat resistant, impact resistant whereas Pegmatite is heat resistant, impact resistant, pressure resistant.
