Archaeological Significance
Formation
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.
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 Diatomite and Blue Granite
Here you can know more about Diatomite and Blue Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Blue Granite consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand 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 Sedimentary Rocks. When we have to compare Diatomite vs Blue Granite, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Blue Granite is available in black, brown, light to dark grey, white colors. Appearance of Diatomite is Soft and that of Blue Granite is Shiny. Properties of rock is another aspect for Diatomite vs Blue Granite. The hardness of Diatomite is 1 and that of Blue Granite is 6-7. The types of Diatomite are Diatomite 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 Diatomite and Blue Granite is white. The specific heat capacity of Diatomite is 0.90 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.Diatomite is heat resistant whereas Blue Granite is heat resistant, impact resistant, pressure resistant.
