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.
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Shonkinite vs Latite 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 Latite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shonkinite and Properties of Latite. Learn more about Shonkinite vs Latite in the next section. The interior uses of Shonkinite include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Latite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Shonkinite and Latite, 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 Latite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Shonkinite and Latite
Here you can know more about Shonkinite and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shonkinite and Latite 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 Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Shonkinite vs Latite, 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, Latite is available in black, brown, green, grey, pink, white colors. Appearance of Shonkinite is Banded and Foilated and that of Latite is Rough. Properties of rock is another aspect for Shonkinite vs Latite. The hardness of Shonkinite is 5.5-6 and that of Latite is 5-5.5. The types of Shonkinite are Igneous rock whereas types of Latite are Rhomb porphyries. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shonkinite and Latite is white. The specific heat capacity of Shonkinite is 0.92 kJ/Kg K and that of Latite 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 Latite is heat resistant, pressure resistant.
