Definition
Borolanite is a variety of Nepheline Syenite and belongs to igneous rocks and contains nepheline-alkali feldspar pseudomorphs which occur as conspicuous white spots in the dark rock matrix
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

Archaeological Significance
Formation
Borolanites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

More about Borolanite and Evaporite
Here you can know more about Borolanite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Borolanite and Evaporite consists of mineral content and compound content. The mineral content of Borolanite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite and mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Igneous Rocks. When we have to compare Borolanite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Borolanite is available in brown, buff, cream, green, grey, pink, white colors whereas, Evaporite is available in green, grey, silver, white colors. Appearance of Borolanite is Banded and Foilated and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Borolanite vs Evaporite. The hardness of Borolanite is 5.5-6 and that of Evaporite is 2-3. The types of Borolanite are - whereas types of Evaporite are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Borolanite and Evaporite is white. The specific heat capacity of Borolanite is 0.84 kJ/Kg K and that of Evaporite 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.Borolanite is heat resistant, impact resistant, wear resistant whereas Evaporite is heat resistant, pressure resistant.
