Definition
Blue Granite is an igneous rock and a variety of Larvikite, notable for the presence of thumbnail-sized blue crystals of feldspar
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone

Archaeological Significance
Formation
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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Blue Granite and Metapelite
Here you can know more about Blue Granite and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Blue Granite and Metapelite consists of mineral content and compound content. The mineral content of Blue Granite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Blue Granite vs Metapelite, the texture, color and appearance plays an important role in determining the type of rock. Blue Granite is available in black, brown, light to dark grey, white colors whereas, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Blue Granite is Shiny and that of Metapelite is Banded. Properties of rock is another aspect for Blue Granite vs Metapelite. The hardness of Blue Granite is 6-7 and that of Metapelite is 5-6. The types of Blue Granite are Granite whereas types of Metapelite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Blue Granite is white while that of Metapelite is . The specific heat capacity of Blue Granite is 0.79 kJ/Kg K and that of Metapelite is 0.72 kJ/Kg K.
