5 Formation

5.1 Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

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

Charnockite 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 Charnockite and Chalk Reserves. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and 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 Charnockite vs Chalk information and Charnockite vs Chalk characteristics in the upcoming sections.
