Archaeological Significance
Formation
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.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Latite vs Dolomite 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. Latite vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Latite and Properties of Dolomite. Learn more about Latite vs Dolomite in the next section. The interior uses of Latite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Latite and Dolomite, they have various applications in construction industry. The uses of Latite in construction industry 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 and that of Dolomite 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, Production of glass and ceramics, Serves as an oil and gas reservoir rock.
More about Latite and Dolomite
Here you can know more about Latite and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Dolomite consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Latite vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Latite is available in black, brown, green, grey, pink, white colors whereas, Dolomite is available in black, brown, green, grey, pink, white colors. Appearance of Latite is Rough and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Latite vs Dolomite. The hardness of Latite is 5-5.5 and that of Dolomite is 3.5-4. The types of Latite are Rhomb porphyries whereas types of Dolomite are Boninite and Jasperoid. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Latite and Dolomite is white. The specific heat capacity of Latite is 0.92 kJ/Kg K and that of Dolomite 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.Latite is heat resistant, pressure resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
