Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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.

Conglomerate vs Tachylite 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. Conglomerate vs Tachylite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Tachylite. Learn more about Conglomerate vs Tachylite in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Tachylite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Conglomerate and Tachylite, they have various applications in construction industry. The uses of Conglomerate in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone and that of Tachylite include Cutting tool, Knives, Landscaping, Scrapers.
More about Conglomerate and Tachylite
Here you can know more about Conglomerate and Tachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Tachylite consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Tachylite includes Feldspar, Olivine. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Tachylite, the texture, color and appearance plays an important role in determining the type of rock. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas, Tachylite is available in black, dark brown colors. Appearance of Conglomerate is Shiny and Rounded and that of Tachylite is Glassy. Properties of rock is another aspect for Conglomerate vs Tachylite. The hardness of Conglomerate is 2-3 and that of Tachylite is 5.5. The types of Conglomerate are Not Available whereas types of Tachylite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate is white while that of Tachylite is vermilion. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Tachylite is 0.56 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Conglomerate is heat resistant whereas Tachylite is heat resistant, impact resistant, wear resistant.
