Formation

Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.

Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

More about Gossan and Turbidite

Here you can know more about Gossan and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gossan and Turbidite 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 Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Gossan vs Turbidite, 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, Turbidite is available in black, brown, green, grey, pink colors. Appearance of Gossan is Dull and Banded and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Gossan vs Turbidite. The hardness of Gossan is 4-5 and that of Turbidite is 3. The types of Gossan are Translocated gossan and Leakage gossan whereas types of Turbidite are Sedimentary rock. 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 Turbidite is white, greenish white or grey. The specific heat capacity of Gossan is 0.24 kJ/Kg K and that of Turbidite is 0.92 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 Turbidite is heat resistant.
