Definition
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals

Archaeological Significance
Formation
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

More about Whiteschist and Syenite
Here you can know more about Whiteschist and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Syenite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica 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 Metamorphic Rocks. When we have to compare Whiteschist vs Syenite, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in green, grey, white colors whereas, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Whiteschist is Banded and Foilated and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Whiteschist vs Syenite. The hardness of Whiteschist is 1.5 and that of Syenite is 5.5-6. The types of Whiteschist are - 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 Whiteschist and Syenite is white. The specific heat capacity of Whiteschist is 0.92 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.Whiteschist is heat resistant whereas Syenite is heat resistant, impact resistant, wear resistant.
