Phyllite vs Shale


Definition

Definition
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles   
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks

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.   
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

Shale vs Phyllite 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 Phyllite Reserves. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks. 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 Phyllite information and Shale vs Phyllite characteristics in the upcoming sections.

Shale vs Phyllite 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 Phyllite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shale and Properties of Phyllite. Learn more about Shale vs Phyllite in the next section. The interior uses of Shale include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Phyllite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Shale and Phyllite, 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 Phyllite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar, Roadstone.

More about Shale and Phyllite

Here you can know more about Shale and Phyllite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shale and Phyllite 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 Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Shale vs Phyllite, 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, Phyllite is available in black to grey, light greenish grey colors. Appearance of Shale is Muddy and that of Phyllite is Crinkled or Wavy. Properties of rock is another aspect for Shale vs Phyllite. The hardness of Shale is 3 and that of Phyllite is 1-2. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale whereas types of Phyllite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shale and Phyllite is white. The specific heat capacity of Shale is 0.39 kJ/Kg K and that of Phyllite 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 Phyllite is heat resistant, pressure resistant, water resistant.
