Chalk vs Blue Granite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Chalk and Blue Granite Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Blue Granite is an igneous rock and a variety of Larvikite, notable for the presence of thumbnail-sized blue crystals of feldspar. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Chalk vs Blue Granite information and Chalk vs Blue Granite characteristics in the upcoming sections.

More about Chalk and Blue Granite

Here you can know more about Chalk and Blue Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Blue Granite consists of mineral content and compound content. The mineral content of Chalk 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 Chalk vs Blue Granite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Blue Granite is available in black, brown, light to dark grey, white colors. Appearance of Chalk is Soft and that of Blue Granite is Shiny. Properties of rock is another aspect for Chalk vs Blue Granite. The hardness of Chalk is 1 and that of Blue Granite is 6-7. The types of Chalk are Not Available whereas types of Blue Granite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk and Blue Granite is white. The specific heat capacity of Chalk 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.Chalk is heat resistant whereas Blue Granite is heat resistant, impact resistant, pressure resistant.
