5.1 Formation
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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Pseudotachylite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Travertine vs Pseudotachylite 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 Travertine and Pseudotachylite Reserves. Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters. Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.. 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 Travertine vs Pseudotachylite information and Travertine vs Pseudotachylite characteristics in the upcoming sections.

Travertine vs Pseudotachylite 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. Travertine vs Pseudotachylite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Travertine and Properties of Pseudotachylite. Learn more about Travertine vs Pseudotachylite in the next section.

More about Travertine and Pseudotachylite

Here you can know more about Travertine and Pseudotachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Pseudotachylite consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Pseudotachylite includes Iron Oxides, Pyroxene, Quartz, Stishovite, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Pseudotachylite, the texture, color and appearance plays an important role in determining the type of rock. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas, Pseudotachylite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Travertine is Fibrous and that of Pseudotachylite is Dull and Soft. Properties of rock is another aspect for Travertine vs Pseudotachylite. The hardness of Travertine is 3-4 and that of Pseudotachylite is 7. The types of Travertine are Not Available whereas types of Pseudotachylite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Travertine is white while that of Pseudotachylite is light to dark brown. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Pseudotachylite 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.Travertine is impact resistant, pressure resistant, wear resistant whereas Pseudotachylite is heat resistant.
