Definition
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction
  
Rhyolite is a fine-grained igneous rock which is rich in silica

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
  
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

Boninite vs Rhyolite 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. Boninite vs Rhyolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Boninite and Properties of Rhyolite. Learn more about Boninite vs Rhyolite in the next section. The interior uses of Boninite include Decorative aggregates, Homes and Kitchens whereas the interior uses of Rhyolite include Decorative aggregates, Homes, Hotels, Interior decoration and Kitchens. Due to some exceptional properties of Boninite and Rhyolite, they have various applications in construction industry. The uses of Boninite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Rhyolite include Arrowheads, As dimension stone, Building houses or walls, Construction aggregate, Cutting tool, For road aggregate, Knives.
More about Boninite and Rhyolite
Here you can know more about Boninite and Rhyolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Rhyolite consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Rhyolite, the texture, color and appearance plays an important role in determining the type of rock. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas, Rhyolite is available in grey, white, light black colors. Appearance of Boninite is Dull and Soft and that of Rhyolite is Banded. Properties of rock is another aspect for Boninite vs Rhyolite. The hardness of Boninite is 7 and that of Rhyolite is 6-7. The types of Boninite are Not Available whereas types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Boninite is white while that of Rhyolite is colorless. The specific heat capacity of Boninite is Not Available and that of Rhyolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Boninite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Rhyolite is heat resistant, wear resistant.
