1 Definition
1.1 Definition
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

5.1 Formation
Slate is a low grade metamorphic rock that is generally formed by metamorphosis of mudstone or shale, under relatively low pressure and temperature conditions.
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.

Slate 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 Slate and Travertine Reserves. Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. 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 Slate vs Travertine information and Slate vs Travertine characteristics in the upcoming sections.

Slate 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. Slate vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Slate and Properties of Travertine. Learn more about Slate vs Travertine in the next section. The interior uses of Slate include Bathrooms, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Slate and Travertine, they have various applications in construction industry. The uses of Slate in construction industry include As dimension stone 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 Slate and Travertine

Here you can know more about Slate and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Slate and Travertine consists of mineral content and compound content. The mineral content of Slate includes Apatite, Biotite, Chlorite, Feldspar, Graphite, Hematite, Kaolinite, Magnetite, Pyrite, Tourmaline, Zircon and mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Slate vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Slate is Dull and that of Travertine is Fibrous. Properties of rock is another aspect for Slate vs Travertine. Hardness of Slate and Travertine is 3-4. The types of Slate are Not Available whereas types of Travertine are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Slate is light to dark brown while that of Travertine is white. The specific heat capacity of Slate is 0.76 kJ/Kg K and that of Travertine is 1.09 kJ/Kg K.
