Chalk vs Pegmatite

Chalk vs Pegmatite 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 Pegmatite Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals. 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 Pegmatite information and Chalk vs Pegmatite characteristics in the upcoming sections.

Chalk vs Pegmatite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Chalk vs Pegmatite characteristics assist us to distinguish and recognize rocks.
