Formation

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.
Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.

Siltstone vs Travertine 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 Siltstone and Travertine Reserves. Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt. Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters. 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 Siltstone vs Travertine information and Siltstone vs Travertine characteristics in the upcoming sections.

Siltstone vs Travertine 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. Siltstone vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Siltstone and Properties of Travertine. Learn more about Siltstone vs Travertine in the next section. The interior uses of Siltstone include Decorative aggregates and Interior decoration whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Siltstone and Travertine, they have various applications in construction industry. The uses of Siltstone in construction industry include Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Travertine include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar.

More about Siltstone and Travertine

Here you can know more about Siltstone and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Siltstone and Travertine 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 Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Siltstone vs Travertine, 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, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Siltstone is Rough and that of Travertine is Fibrous. Properties of rock is another aspect for Siltstone vs Travertine. The hardness of Siltstone is 6-7 and that of Travertine is 3-4. The types of Siltstone are Siltstone whereas types of Travertine are Thermal Travertine and Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Siltstone and Travertine is white. The specific heat capacity of Siltstone is 0.84 kJ/Kg K and that of Travertine is 1.09 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 Travertine is impact resistant, pressure resistant, wear resistant.
