Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.   
Picrite 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.

Basanite  vs Picrite 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 Basanite  and Picrite Reserves. Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. 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 Basanite  vs Picrite information and Basanite  vs Picrite characteristics in the upcoming sections.

Basanite  vs Picrite 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. Basanite  vs Picrite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite  and Properties of Picrite. Learn more about Basanite  vs Picrite in the next section. The interior uses of Basanite  include Decorative aggregates and Homes whereas the interior uses of Picrite include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Basanite  and Picrite, they have various applications in construction industry. The uses of Basanite  in construction industry include Arrowheads, Construction aggregate, Cutting tool, Spear points and that of Picrite include As a sintering agent in steel industry to process iron ore, Cement manufacture, For road aggregate, Manufacture of magnesium and dolomite refractories, Roadstone, Used for flooring, stair treads, borders and window sills..

More about Basanite  and Picrite

Here you can know more about Basanite  and Picrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite  and Picrite consists of mineral content and compound content. The mineral content of Basanite  includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite. You can also check out the list of all Igneous Rocks. When we have to compare Basanite  vs Picrite, the texture, color and appearance plays an important role in determining the type of rock. Basanite  is available in black, brown, green, grey, red, white colors whereas, Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors. Appearance of Basanite  is Glassy or Pearly and that of Picrite is Rough and Shiny. Properties of rock is another aspect for Basanite  vs Picrite. The hardness of Basanite  is 7 and that of Picrite is 6.8. The types of Basanite  are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Picrite are Oceanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basanite  is white while that of Picrite is white, greenish white or grey. The specific heat capacity of Basanite  is 0.74 kJ/Kg K and that of Picrite is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Basanite  is heat resistant, impact resistant, pressure resistant, wear resistant whereas Picrite is heat resistant.
