Definition
Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

Formation
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

Gossan vs Diamictite 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 Diamictite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Gossan and Properties of Diamictite. Learn more about Gossan vs Diamictite in the next section. The interior uses of Gossan include Countertops, Decorative aggregates and Interior decoration whereas the interior uses of Diamictite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Gossan and Diamictite, 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 Diamictite include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone.
More about Gossan and Diamictite
Here you can know more about Gossan and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gossan and Diamictite 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 Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Gossan vs Diamictite, 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, Diamictite is available in brown, buff colors. Appearance of Gossan is Dull and Banded and that of Diamictite is Banded. Properties of rock is another aspect for Gossan vs Diamictite. The hardness of Gossan is 4-5 and that of Diamictite is 2-3. The types of Gossan are Translocated gossan and Leakage gossan whereas types of Diamictite are Bedded Diamictite and Laminated Diamictite. 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 Diamictite is light to dark brown. The specific heat capacity of Gossan is 0.24 kJ/Kg K and that of Diamictite is 0.75 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 Diamictite is heat resistant, impact resistant.
