Chalk vs Gabbro 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 Gabbro Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt. 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 Gabbro information and Chalk vs Gabbro characteristics in the upcoming sections.

Chalk vs Gabbro 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 Gabbro characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Gabbro. Learn more about Chalk vs Gabbro in the next section.
