5 Formation

5.1 Formation

Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

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.

Migmatite 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 Migmatite and Shale Reserves. Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components. 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 Migmatite vs Shale information and Migmatite vs Shale characteristics in the upcoming sections.

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

More about Migmatite and Shale

Here you can know more about Migmatite and Shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Migmatite and Shale consists of mineral content and compound content. The mineral content of Migmatite includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon 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 Metamorphic Rocks. When we have to compare Migmatite vs Shale, the texture, color and appearance plays an important role in determining the type of rock. Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors whereas, Shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Migmatite is Dull, Banded and Foilated and that of Shale is Muddy. Properties of rock is another aspect for Migmatite vs Shale. The hardness of Migmatite is 5.5-6.5 and that of Shale is 3. The types of Migmatite are Diatexites and Metatexites whereas types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale.
