Formation

Formation

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 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.

Pseudotachylite 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 Pseudotachylite and Travertine Reserves. Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.. 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 Pseudotachylite vs Travertine information and Pseudotachylite vs Travertine characteristics in the upcoming sections.

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

Due to some exceptional properties of Pseudotachylite and Travertine, they have various applications in construction industry. The uses of Pseudotachylite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement 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 Pseudotachylite and Travertine

Here you can know more about Pseudotachylite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pseudotachylite and Travertine consists of mineral content and compound content. The mineral content of Pseudotachylite includes Iron Oxides, Pyroxene, Quartz, Stishovite, Sulfides 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 Pseudotachylite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Pseudotachylite is available in black, brown, green, grey, pink, white colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Pseudotachylite is Dull and Soft and that of Travertine is Fibrous. Properties of rock is another aspect for Pseudotachylite vs Travertine. The hardness of Pseudotachylite is 7 and that of Travertine is 3-4. The types of Pseudotachylite are Cataclastic rock 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 Pseudotachylite is light to dark brown while that of Travertine is white. The specific heat capacity of Pseudotachylite is 0.92 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.Pseudotachylite is heat resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
