Formation
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 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 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. Diatomite vs Arkose characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diatomite and Properties of Arkose. Learn more about Diatomite vs Arkose in the next section. The interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Arkose include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Diatomite and Arkose, they have various applications in construction industry. The uses of Diatomite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Source of calcium 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 Diatomite and Arkose
Here you can know more about Diatomite and Arkose. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Arkose consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all . When we have to compare Diatomite vs Arkose, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Arkose is available in reddish brown colors. Appearance of Diatomite is Soft and that of Arkose is Rough and Dull. Properties of rock is another aspect for Diatomite vs Arkose. The hardness of Diatomite is 1 and that of Arkose is 6-7. The types of Diatomite are Not Available whereas types of Arkose are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diatomite and Arkose is white. The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Arkose is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diatomite is heat resistant whereas Arkose is heat resistant, impact resistant, pressure resistant.
