Gossan vs Claystone


Definition

Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay  
Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.

Formation

Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.  
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.

Claystone 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 Claystone and Gossan Reserves. Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay. 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 Claystone vs Gossan information and Claystone vs Gossan characteristics in the upcoming sections.

Claystone vs Gossan 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. Claystone vs Gossan characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Claystone and Properties of Gossan. Learn more about Claystone vs Gossan in the next section. The interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration whereas the interior uses of Gossan include Countertops, Decorative aggregates and Interior decoration. Due to some exceptional properties of Claystone and Gossan, they have various applications in construction industry. The uses of Claystone in construction industry include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Gossan include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.

More about Claystone and Gossan

Here you can know more about Claystone and Gossan. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Gossan consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Gossan includes Apatite, Augite, Biotite, Bronzite, Calcite, Chert, Epidote, Feldspar, Hornblende, Micas, Plagioclase, Pyroxene, Quartz, Sulfides, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Gossan, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Gossan is available in brown, brown- black, gold, green, rust colors. Appearance of Claystone is Rough and Dull and that of Gossan is Dull and Banded. Properties of rock is another aspect for Claystone vs Gossan. The hardness of Claystone is 3.5-4 and that of Gossan is 4-5. The types of Claystone are Claystone whereas types of Gossan are Translocated gossan and Leakage gossan. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone is white while that of Gossan is white to grey. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Gossan is 0.24 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Gossan is heat resistant, impact resistant, pressure resistant.
