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.
Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.

More about Blue Granite and Travertine
Here you can know more about Blue Granite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Blue Granite and Travertine 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 Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Blue Granite vs Travertine, 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, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Blue Granite is Shiny and that of Travertine is Fibrous. Properties of rock is another aspect for Blue Granite vs Travertine. The hardness of Blue Granite is 6-7 and that of Travertine is 3-4. The types of Blue Granite are Granite whereas types of Travertine are Thermal Travertine and Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Blue Granite and Travertine is white. The specific heat capacity of Blue Granite is 0.79 kJ/Kg K and that of Travertine is 1.09 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 Travertine is impact resistant, pressure resistant, wear resistant.
