Definition
Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

Formation
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Gossan vs Laterite 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 Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Gossan and Properties of Laterite. Learn more about Gossan vs Laterite in the next section. The interior uses of Gossan include Countertops, Decorative aggregates and Interior decoration whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Gossan and Laterite, they have various applications in construction industry. The uses of Gossan in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate and that of Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Gossan and Laterite
Here you can know more about Gossan and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gossan and Laterite consists of mineral content and compound content. The mineral content of Gossan includes Apatite, Augite, Biotite, Bronzite, Calcite, Chert, Epidote, Feldspar, Hornblende, Micas, Plagioclase, Pyroxene, Quartz, Sulfides, Zircon and mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Gossan vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Gossan is available in brown, brown- black, gold, green, rust colors whereas, Laterite is available in brown, buff, red colors. Appearance of Gossan is Dull and Banded and that of Laterite is Rough and Banded. Properties of rock is another aspect for Gossan vs Laterite. The hardness of Gossan is 4-5 and that of Laterite is 2. The types of Gossan are Translocated gossan and Leakage gossan whereas types of Laterite 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 Laterite is white. The specific heat capacity of Gossan is 0.24 kJ/Kg K and that of Laterite is Not Available. 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 Laterite is heat resistant, pressure resistant.
