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.   
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

Blue Granite vs Chalk 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 Blue Granite and Chalk Reserves. Blue Granite is an igneous rock and a variety of Larvikite, notable for the presence of thumbnail-sized blue crystals of feldspar. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. 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 Blue Granite vs Chalk information and Blue Granite vs Chalk characteristics in the upcoming sections.
