Kenyte vs Shale


Definition

Definition
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles  
Kenyte is a variety of porphyritic phonolite or trachyte rock with rhomb shaped phenocrysts of anorthoclase with variable olivine and augite in a glassy matrix  

History
  
  

Origin

Etymology
From German Schalstein laminated limestone, and Schalgebirge layer of stone in stratified rock. From Old English scealu in its base sense of- thing that divides or separate,  
From the mountain ranges- Mount Kenya and is named by J. W. Gregory in 1900

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.  
Kenyte is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Shale vs Kenyte 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 Kenyte Reserves. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. Kenyte is a variety of porphyritic phonolite or trachyte rock with rhomb shaped phenocrysts of anorthoclase with variable olivine and augite in a glassy matrix. 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 Kenyte information and Shale vs Kenyte characteristics in the upcoming sections.

Shale vs Kenyte 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 Kenyte characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shale and Properties of Kenyte. Learn more about Shale vs Kenyte in the next section. The interior uses of Shale include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Kenyte include Decorative aggregates, Entryways, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Shale and Kenyte, 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 Kenyte include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics.

More about Shale and Kenyte

Here you can know more about Shale and Kenyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shale and Kenyte 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 Kenyte includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Shale vs Kenyte, 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, Kenyte is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Shale is Muddy and that of Kenyte is Banded and Foilated. Properties of rock is another aspect for Shale vs Kenyte. The hardness of Shale is 3 and that of Kenyte is 5.5-6. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale whereas types of Kenyte are Foidolite. 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 Kenyte is white, greenish white or grey. The specific heat capacity of Shale is 0.39 kJ/Kg K and that of Kenyte is 0.84 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 Kenyte is heat resistant, impact resistant, wear resistant.
