Shale vs Adakite


Adakite vs Shale


Definition

Definition
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles   
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

Formation

Formation
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.   
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

Shale vs Adakite 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 Adakite Reserves. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs. 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 Adakite information and Shale vs Adakite characteristics in the upcoming sections.

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

More about Shale and Adakite

Here you can know more about Shale and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shale and Adakite consists of mineral content and compound content. The mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides and mineral content of Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Shale vs Adakite, the texture, color and appearance plays an important role in determining the type of rock. Shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Adakite is available in black, brown, light to dark grey colors. Appearance of Shale is Muddy and that of Adakite is Dull and Soft. Properties of rock is another aspect for Shale vs Adakite. The hardness of Shale is 3 and that of Adakite is 3-4. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale whereas types of Adakite 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 Adakite is bluish black. The specific heat capacity of Shale is 0.39 kJ/Kg K and that of Adakite is Not Available. 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 Adakite is heat resistant, pressure resistant, wear resistant.
