Definition
Shonkinite is a rare, dark-coloured and intrusive igneous rock which contains augite and orthoclase feldspar as its primary constituents
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Archaeological Significance
Formation
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Shonkinite vs Claystone 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. Shonkinite vs Claystone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shonkinite and Properties of Claystone. Learn more about Shonkinite vs Claystone in the next section. The interior uses of Shonkinite include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Shonkinite and Claystone, they have various applications in construction industry. The uses of Shonkinite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Claystone include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Shonkinite and Claystone
Here you can know more about Shonkinite and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shonkinite and Claystone consists of mineral content and compound content. The mineral content of Shonkinite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Shonkinite vs Claystone, the texture, color and appearance plays an important role in determining the type of rock. Shonkinite is available in brown, buff, cream, green, grey, pink, white colors whereas, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Shonkinite is Banded and Foilated and that of Claystone is Rough and Dull. Properties of rock is another aspect for Shonkinite vs Claystone. The hardness of Shonkinite is 5.5-6 and that of Claystone is 3.5-4. The types of Shonkinite are Igneous rock whereas types of Claystone are Claystone. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shonkinite and Claystone is white. The specific heat capacity of Shonkinite is 0.92 kJ/Kg K and that of Claystone 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.Shonkinite is heat resistant, impact resistant, wear resistant whereas Claystone is heat resistant, impact resistant.
