Formation
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.
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.

Arkose 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. Arkose vs Diatomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Arkose and Properties of Diatomite. Learn more about Arkose vs Diatomite in the next section. The interior uses of Arkose include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Arkose and Diatomite, they have various applications in construction industry. The uses of Arkose in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar and that of Diatomite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Source of calcium.
More about Arkose and Diatomite
Here you can know more about Arkose and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Arkose and Diatomite consists of mineral content and compound content.

You can also check out the list of all . When we have to compare Arkose vs Diatomite, the texture, color and appearance plays an important role in determining the type of rock. Arkose is available in reddish brown colors whereas, Diatomite is available in grey, white, yellow colors. Appearance of Arkose is Rough and Dull and that of Diatomite is Soft. Properties of rock is another aspect for Arkose vs Diatomite. The hardness of Arkose is 6-7 and that of Diatomite is 1. The types of Arkose 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 Arkose and Diatomite is white. The specific heat capacity of Arkose 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.Arkose is heat resistant, impact resistant, pressure resistant whereas Diatomite is heat resistant.
