Definition
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles
Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass

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.
Shoshonite 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 Shoshonite 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 Shoshonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shale and Properties of Shoshonite. Learn more about Shale vs Shoshonite in the next section. The interior uses of Shale include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Shoshonite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Shale and Shoshonite, 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 Shoshonite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Shale and Shoshonite
Here you can know more about Shale and Shoshonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shale and Shoshonite 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 Shoshonite includes Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Shale vs Shoshonite, 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, Shoshonite is available in brown- black, dark brown colors. Appearance of Shale is Muddy and that of Shoshonite is Dull. Properties of rock is another aspect for Shale vs Shoshonite. The hardness of Shale is 3 and that of Shoshonite is 6. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale whereas types of Shoshonite 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 Shoshonite is white to grey. The specific heat capacity of Shale is 0.39 kJ/Kg K and that of Shoshonite 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 Shoshonite is heat resistant, pressure resistant.
