Definition
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

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.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

Arkose vs Diamictite 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 Diamictite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Arkose and Properties of Diamictite. Learn more about Arkose vs Diamictite in the next section. The interior uses of Arkose include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Diamictite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Arkose and Diamictite, 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 Diamictite include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone.
More about Arkose and Diamictite
Here you can know more about Arkose and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Arkose and Diamictite consists of mineral content and compound content. The mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Arkose vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Arkose is available in reddish brown colors whereas, Diamictite is available in brown, buff colors. Appearance of Arkose is Rough and Dull and that of Diamictite is Banded. Properties of rock is another aspect for Arkose vs Diamictite. The hardness of Arkose is 6-7 and that of Diamictite is 2-3. The types of Arkose are Not Available whereas types of Diamictite are Bedded Diamictite and Laminated Diamictite.
