5 Formation

5.1 Formation

Tachylite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

Tachylite vs Diabase 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 Tachylite and Diabase Reserves. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. 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 Tachylite vs Diabase information and Tachylite vs Diabase characteristics in the upcoming sections.

Tachylite vs Diabase 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. Tachylite vs Diabase characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tachylite and Properties of Diabase. Learn more about Tachylite vs Diabase in the next section. The interior uses of Tachylite include Decorative aggregates and Interior decoration whereas the interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Tachylite and Diabase, they have various applications in construction industry. The uses of Tachylite in construction industry include Cutting tool, Knives, Landscaping, Scrapers and that of Diabase include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Tachylite and Diabase

Here you can know more about Tachylite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Diabase consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Igneous Rocks. When we have to compare Tachylite vs Diabase, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Diabase is available in dark grey to black colors. Appearance of Tachylite is Glassy and that of Diabase is Vesicular. Properties of rock is another aspect for Tachylite vs Diabase. The hardness of Tachylite is 5.5 and that of Diabase is 7. The types of Tachylite are Not Available whereas types of Diabase are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tachylite is vermilion while that of Diabase is black. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Diabase is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Tachylite is heat resistant, impact resistant, wear resistant whereas Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
