Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

Basanite vs Oolite 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 Oolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite and Properties of Oolite. Learn more about Basanite vs Oolite in the next section. The interior uses of Basanite include Decorative aggregates and Homes whereas the interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Basanite and Oolite, 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 Oolite include Cement manufacture, Cobblestones, Landscaping.
More about Basanite and Oolite
Here you can know more about Basanite and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Oolite consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Basanite vs Oolite, 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, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Basanite is Glassy or Pearly and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Basanite vs Oolite. The hardness of Basanite is 7 and that of Oolite is 3-4. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Oolite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basanite and Oolite is white. The specific heat capacity of Basanite is 0.74 kJ/Kg K and that of Oolite is Not Available. 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 Oolite is heat resistant, wear resistant.
