Definition
Blue Granite is an igneous rock and a variety of Larvikite, notable for the presence of thumbnail-sized blue crystals of feldspar
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

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.
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

More about Blue Granite and Shale
Here you can know more about Blue Granite and Shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Blue Granite and Shale 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 Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Blue Granite vs Shale, 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, Shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Blue Granite is Shiny and that of Shale is Muddy. Properties of rock is another aspect for Blue Granite vs Shale. The hardness of Blue Granite is 6-7 and that of Shale is 3. The types of Blue Granite are Granite whereas types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale.
