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
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar

Archaeological Significance
Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

Boninite vs Arkose 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 Arkose characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Boninite and Properties of Arkose. Learn more about Boninite vs Arkose in the next section. The interior uses of Boninite include Decorative aggregates, Homes and Kitchens whereas the interior uses of Arkose include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Boninite and Arkose, 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 Arkose include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Boninite and Arkose
Here you can know more about Boninite and Arkose. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Arkose consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Arkose, the texture, color and appearance plays an important role in determining the type of rock. Boninite is available in bluish - grey, brown, green, grey colors whereas, Arkose is available in reddish brown colors. Appearance of Boninite is Dull and Soft and that of Arkose is Rough and Dull. Properties of rock is another aspect for Boninite vs Arkose. The hardness of Boninite is 7 and that of Arkose is 6-7. The types of Boninite are Basalt whereas types of Arkose are Arkose. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Boninite and Arkose is white. The specific heat capacity of Boninite is 0.84 kJ/Kg K and that of Arkose is 0.78 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 Arkose is heat resistant, impact resistant, pressure resistant.
