Chalk vs Nephelinite

Chalk vs Nephelinite 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 Nephelinite Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).. 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 Nephelinite information and Chalk vs Nephelinite characteristics in the upcoming sections.
