Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth

Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

Basanite vs Basalt 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 Basalt characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite and Properties of Basalt. Learn more about Basanite vs Basalt in the next section. The interior uses of Basanite include Decorative aggregates and Homes whereas the interior uses of Basalt include Floor tiles, Homes, Hotels and Kitchens. Due to some exceptional properties of Basanite and Basalt, 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 Basalt include Arrowheads, As dimension stone, Cobblestones, Cutting tool, Rail track ballast, Roadstone.
More about Basanite and Basalt
Here you can know more about Basanite and Basalt. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Basalt consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Basalt includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Basanite vs Basalt, 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, Basalt is available in black, brown, light to dark grey colors. Appearance of Basanite is Glassy or Pearly and that of Basalt is Dull and Soft. Properties of rock is another aspect for Basanite vs Basalt. The hardness of Basanite is 7 and that of Basalt is 6. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Basalt are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. 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 Basalt is white to grey. The specific heat capacity of Basanite is 0.74 kJ/Kg K and that of Basalt 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.Basanite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Basalt is heat resistant, pressure resistant, wear resistant.
