Gossan vs Chalk

Gossan 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 Gossan and Chalk Reserves. Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.. 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 Gossan vs Chalk information and Gossan vs Chalk characteristics in the upcoming sections.

Gossan vs Chalk 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. Gossan vs Chalk characteristics assist us to distinguish and recognize rocks.

Gossan is available in brown, brown- black, gold, green, rust colors whereas, Chalk is available in grey, white, yellow colors. Appearance of Gossan is Dull and Banded and that of Chalk is Soft. Properties of rock is another aspect for Gossan vs Chalk. The hardness of Gossan is 4-5 and that of Chalk is 1. The types of Gossan are Translocated gossan and Leakage gossan whereas types of Chalk are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gossan is white to grey while that of Chalk is white. The specific heat capacity of Gossan is 0.24 kJ/Kg K and that of Chalk is 0.90 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Gossan is heat resistant, impact resistant, pressure resistant whereas Chalk is heat resistant.
