Definition
Jaspillite is an iron rich chemically formed rock which is common in banded iron formation rocks
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

Formation
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.
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.

Jaspillite 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. Jaspillite vs Tachylite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Jaspillite and Properties of Tachylite. Learn more about Jaspillite vs Tachylite in the next section. The interior uses of Jaspillite include Decorative aggregates and Interior decoration whereas the interior uses of Tachylite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Jaspillite and Tachylite, they have various applications in construction industry. The uses of Jaspillite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Tachylite include Cutting tool, Knives, Landscaping, Scrapers.
More about Jaspillite and Tachylite
Here you can know more about Jaspillite and Tachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jaspillite and Tachylite consists of mineral content and compound content. The mineral content of Jaspillite includes Coesite, Quartz, Sand and mineral content of Tachylite includes Feldspar, Olivine. You can also check out the list of all Sedimentary Rocks. When we have to compare Jaspillite vs Tachylite, the texture, color and appearance plays an important role in determining the type of rock. Jaspillite is available in red, reddish brown colors whereas, Tachylite is available in black, dark brown colors. Appearance of Jaspillite is Banded and Glassy and that of Tachylite is Glassy. Properties of rock is another aspect for Jaspillite vs Tachylite. The hardness of Jaspillite is 3 and that of Tachylite is 5.5. The types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type 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 Jaspillite is white while that of Tachylite is vermilion. The specific heat capacity of Jaspillite is 3.20 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.Jaspillite is heat resistant, impact resistant, wear resistant whereas Tachylite is heat resistant, impact resistant, wear resistant.
