Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Granophyre 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 Granophyre 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 Granophyre characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite and Properties of Granophyre. Learn more about Basanite vs Granophyre in the next section. The interior uses of Basanite include Decorative aggregates and Homes whereas the interior uses of Granophyre include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Basanite and Granophyre, 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 Granophyre include As dimension stone.
More about Basanite and Granophyre
Here you can know more about Basanite and Granophyre. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Granophyre consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Basanite vs Granophyre, 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, Granophyre is available in black, grey, orange, pink, white colors. Appearance of Basanite is Glassy or Pearly and that of Granophyre is Veined or Pebbled. Properties of rock is another aspect for Basanite vs Granophyre. The hardness of Basanite is 7 and that of Granophyre is 6-7. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Granophyre 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 Granophyre is white. The specific heat capacity of Basanite is 0.74 kJ/Kg K and that of Granophyre is 0.79 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 Granophyre is heat resistant, wear resistant.
