Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

Boninite vs Diatomite 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 Diatomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Boninite and Properties of Diatomite. Learn more about Boninite vs Diatomite in the next section. The interior uses of Boninite include Decorative aggregates, Homes and Kitchens whereas the interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Boninite and Diatomite, 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 Diatomite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Source of calcium.
More about Boninite and Diatomite
Here you can know more about Boninite and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Diatomite consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Diatomite, 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, Diatomite is available in grey, white, yellow colors. Appearance of Boninite is Dull and Soft and that of Diatomite is Soft. Properties of rock is another aspect for Boninite vs Diatomite. The hardness of Boninite is 7 and that of Diatomite is 1. The types of Boninite are Not Available whereas types of Diatomite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Boninite and Diatomite is white. The specific heat capacity of Boninite is Not Available and that of Diatomite is 0.90 kJ/Kg K. 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 Diatomite is heat resistant.
