Definition
Blue Granite is an igneous rock and a variety of Larvikite, notable for the presence of thumbnail-sized blue crystals of feldspar
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations

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.
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

More about Blue Granite and Mudstone
Here you can know more about Blue Granite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Blue Granite and Mudstone 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 Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Blue Granite vs Mudstone, 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, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Blue Granite is Shiny and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Blue Granite vs Mudstone. The hardness of Blue Granite is 6-7 and that of Mudstone is 2-3. The types of Blue Granite are Granite whereas types of Mudstone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Blue Granite and Mudstone is white. The specific heat capacity of Blue Granite is 0.79 kJ/Kg K and that of Mudstone is 0.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Blue Granite is heat resistant, impact resistant, pressure resistant whereas Mudstone is heat resistant, impact resistant.
