Definition
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth
Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.

Archaeological Significance
Formation
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.

Diatomite 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. Diatomite vs Gossan characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diatomite and Properties of Gossan. Learn more about Diatomite vs Gossan in the next section. The interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Gossan include Countertops, Decorative aggregates and Interior decoration. Due to some exceptional properties of Diatomite and Gossan, they have various applications in construction industry.

More about Diatomite and Gossan
Here you can know more about Diatomite and Gossan. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Gossan consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand 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 Diatomite vs Gossan, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Gossan is available in brown, brown- black, gold, green, rust colors. Appearance of Diatomite is Soft and that of Gossan is Dull and Banded. Properties of rock is another aspect for Diatomite vs Gossan. The hardness of Diatomite is 1 and that of Gossan is 4-5. The types of Diatomite are Diatomite 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 Diatomite is white while that of Gossan is white to grey. The specific heat capacity of Diatomite is 0.90 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.Diatomite is heat resistant whereas Gossan is heat resistant, impact resistant, pressure resistant.
