Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar
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

Formation

Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
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.

Diabase vs Shoshonite 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 Diabase and Shoshonite Reserves. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. 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. 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 Diabase vs Shoshonite information and Diabase vs Shoshonite characteristics in the upcoming sections.

Diabase 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. Diabase vs Shoshonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Shoshonite. Learn more about Diabase vs Shoshonite in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Shoshonite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Diabase and Shoshonite, they have various applications in construction industry. The uses of Diabase in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Shoshonite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.

More about Diabase and Shoshonite

Here you can know more about Diabase and Shoshonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Shoshonite consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Shoshonite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Diabase vs Shoshonite, the texture, color and appearance plays an important role in determining the type of rock. Diabase is available in dark grey to black colors whereas, Shoshonite is available in brown- black, dark brown colors. Appearance of Diabase is Vesicular and that of Shoshonite is Dull. Properties of rock is another aspect for Diabase vs Shoshonite. The hardness of Diabase is 7 and that of Shoshonite is 6. The types of Diabase are Dolerite whereas types of Shoshonite are Intermediate volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diabase is black while that of Shoshonite is white to grey. The specific heat capacity of Diabase is 0.84 kJ/Kg K and that of Shoshonite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diabase is heat resistant, impact resistant, pressure resistant, wear resistant whereas Shoshonite is heat resistant, pressure resistant.
