Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

Basanite vs Pumice 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 Pumice characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite and Properties of Pumice. Learn more about Basanite vs Pumice in the next section. The interior uses of Basanite include Decorative aggregates and Homes whereas the interior uses of Pumice include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Basanite and Pumice, 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 Pumice include As dimension stone, Cement manufacture, For road aggregate, In landscaping and horticulture, Making natural cement, Production of lightweight concrete blocks.
More about Basanite and Pumice
Here you can know more about Basanite and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Pumice consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Basanite vs Pumice, 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, Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Basanite is Glassy or Pearly and that of Pumice is Vesicular. Properties of rock is another aspect for Basanite vs Pumice. The hardness of Basanite is 7 and that of Pumice is 6. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Pumice are Scoria. 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 Pumice is white, greenish white or grey. The specific heat capacity of Basanite is 0.74 kJ/Kg K and that of Pumice is 0.87 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 Pumice is impact resistant, pressure resistant.
