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
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals

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.
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

More about Litchfieldite and Syenite
Here you can know more about Litchfieldite and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Litchfieldite and Syenite 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 Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Litchfieldite vs Syenite, 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, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Litchfieldite is Banded and Foilated and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Litchfieldite vs Syenite. Hardness of Litchfieldite and Syenite is 5.5-6. The types of Litchfieldite are Borolanite and Litchfieldite whereas types of Syenite are Shonkinite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Litchfieldite and Syenite is white. The specific heat capacity of Litchfieldite is 0.79 kJ/Kg K and that of Syenite 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 Syenite is heat resistant, impact resistant, wear resistant.
