Formation
Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.
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 Siltstone and Turbidite
Here you can know more about Siltstone and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Siltstone and Turbidite consists of mineral content and compound content. The mineral content of Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Sedimentary Rocks. When we have to compare Siltstone vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Siltstone is available in brown, red, reddish brown colors whereas, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Siltstone is Rough and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Siltstone vs Turbidite. The hardness of Siltstone is 6-7 and that of Turbidite is 3. The types of Siltstone are Not Available whereas types of Turbidite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Siltstone is white while that of Turbidite is white, greenish white or grey. The specific heat capacity of Siltstone is Not Available 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.Siltstone is heat resistant, impact resistant, pressure resistant, water resistant whereas Turbidite is heat resistant.
