5 Formation
5.1 Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

Flint vs Shale 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 Flint and Shale Reserves. Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. 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 Flint vs Shale information and Flint vs Shale characteristics in the upcoming sections.

Flint vs Shale 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. Flint vs Shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Flint and Properties of Shale. Learn more about Flint vs Shale in the next section. The interior uses of Flint include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Shale include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Flint and Shale, they have various applications in construction industry. The uses of Flint in construction industry include Arrowheads, Cutting tool, Spear points and that of Shale include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.

More about Flint and Shale

Here you can know more about Flint and Shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Flint and Shale consists of mineral content and compound content. The mineral content of Flint includes Silicon and mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Flint vs Shale, the texture, color and appearance plays an important role in determining the type of rock. Flint is available in black, brown, green, grey, red, white colors whereas, Shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Flint is Glassy or Pearly and that of Shale is Muddy. Properties of rock is another aspect for Flint vs Shale. The hardness of Flint is 7 and that of Shale is 3. The types of Flint are Not Available whereas types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Flint and Shale is white. The specific heat capacity of Flint is 0.74 kJ/Kg K and that of Shale is 0.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Flint is heat resistant, impact resistant, pressure resistant, wear resistant whereas Shale is heat resistant, impact resistant.
