Archaeological Significance
Formation
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Blue Granite is an igneous rock which is a variety of Larvikite and is known mainly for the presence of thumbnail-sized crystals of feldspar.

More about Syenite and Blue Granite
Here you can know more about Syenite and Blue Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Syenite and Blue Granite consists of mineral content and compound content. The mineral content of Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Blue Granite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Syenite vs Blue Granite, the texture, color and appearance plays an important role in determining the type of rock. Syenite is available in brown, buff, cream, green, grey, pink, white colors whereas, Blue Granite is available in black, brown, light to dark grey, white colors. Appearance of Syenite is Banded and Foilated and that of Blue Granite is Shiny. Properties of rock is another aspect for Syenite vs Blue Granite. The hardness of Syenite is 5.5-6 and that of Blue Granite is 6-7. The types of Syenite are Shonkinite whereas types of Blue Granite are Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Syenite and Blue Granite is white. The specific heat capacity of Syenite is 0.92 kJ/Kg K and that of Blue Granite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Syenite is heat resistant, impact resistant, wear resistant whereas Blue Granite is heat resistant, impact resistant, pressure resistant.
