Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows

Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.

Basanite vs Ignimbrite 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 Ignimbrite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite and Properties of Ignimbrite. Learn more about Basanite vs Ignimbrite in the next section. The interior uses of Basanite include Decorative aggregates and Homes whereas the interior uses of Ignimbrite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Basanite and Ignimbrite, 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 Ignimbrite include Building houses or walls, Construction aggregate.
More about Basanite and Ignimbrite
Here you can know more about Basanite and Ignimbrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Ignimbrite consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Ignimbrite includes Apatite, Biotite, Calcite, Chlorite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Basanite vs Ignimbrite, 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, Ignimbrite is available in beige, black, brown, grey, pink, white colors. Appearance of Basanite is Glassy or Pearly and that of Ignimbrite is Dull, Vesicular and Foilated. Properties of rock is another aspect for Basanite vs Ignimbrite. The hardness of Basanite is 7 and that of Ignimbrite is 4-6. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Ignimbrite 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 Ignimbrite is white. The specific heat capacity of Basanite is 0.74 kJ/Kg K and that of Ignimbrite is 0.20 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 Ignimbrite is heat resistant, impact resistant, pressure resistant, wear resistant.
