Chalk vs Gossan

Chalk vs Gossan 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 Gossan Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.. 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 Gossan information and Chalk vs Gossan characteristics in the upcoming sections.

Chalk vs Gossan Characteristics
