Formation

Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.   
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

Jadeitite 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 Jadeitite and Chalk Reserves. Jadeitite is a metamorphic rock usually found in blueschist grade metamorphic terrains. 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 Jadeitite vs Chalk information and Jadeitite vs Chalk characteristics in the upcoming sections.
