Definition
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Arkose vs Talc carbonate 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 Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Arkose and Properties of Talc carbonate. Learn more about Arkose vs Talc carbonate in the next section. The interior uses of Arkose include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Arkose and Talc carbonate, 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 Talc carbonate include Source of calcium.
More about Arkose and Talc carbonate
Here you can know more about Arkose and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Arkose and Talc carbonate consists of mineral content and compound content. The mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Sedimentary Rocks. When we have to compare Arkose vs Talc carbonate, the texture, color and appearance plays an important role in determining the type of rock. Arkose is available in reddish brown colors whereas, Talc carbonate is available in colourless, grey, white colors. Appearance of Arkose is Rough and Dull and that of Talc carbonate is Soft. Properties of rock is another aspect for Arkose vs Talc carbonate. The hardness of Arkose is 6-7 and that of Talc carbonate is 1-2. The types of Arkose are Not Available whereas types of Talc carbonate 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 Talc carbonate is white. The specific heat capacity of Arkose is Not Available and that of Talc carbonate is 0.92 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 Talc carbonate is heat resistant, wear resistant.
