Definition
Litchfieldite is a rare igneous rock which is coarse-grained, foliated and a variety of nepheline syenite, sometimes also called as nepheline syenite gneiss or gneissic nepeheline syenite

Archaeological Significance
Formation
Litchfieldite 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.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

More about Litchfieldite and Evaporite
Here you can know more about Litchfieldite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Litchfieldite and Evaporite consists of mineral content and compound content. The mineral content of Litchfieldite 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 Litchfieldite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Litchfieldite is available in brown, buff, cream, green, grey, pink, white colors whereas, Evaporite is available in green, grey, silver, white colors. Appearance of Litchfieldite is Banded and Foilated and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Litchfieldite vs Evaporite. The hardness of Litchfieldite is 5.5-6 and that of Evaporite is 2-3. The types of Litchfieldite are Borolanite and Litchfieldite 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 Litchfieldite and Evaporite is white. The specific heat capacity of Litchfieldite is 0.79 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.Litchfieldite is heat resistant, impact resistant, wear resistant whereas Evaporite is heat resistant, pressure resistant.
