Definition
Jaspillite is an iron rich chemically formed rock which is common in banded iron formation rocks
Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

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.
Felsite 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 Felsite 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 Felsite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Jaspillite and Properties of Felsite. Learn more about Jaspillite vs Felsite in the next section. The interior uses of Jaspillite include Decorative aggregates and Interior decoration whereas the interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Jaspillite and Felsite, 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 Felsite include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.
More about Jaspillite and Felsite
Here you can know more about Jaspillite and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jaspillite and Felsite consists of mineral content and compound content. The mineral content of Jaspillite includes Coesite, Quartz, Sand and mineral content of Felsite includes Feldspar, Iron Oxides. You can also check out the list of all Sedimentary Rocks. When we have to compare Jaspillite vs Felsite, the texture, color and appearance plays an important role in determining the type of rock. Jaspillite is available in red, reddish brown colors whereas, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Jaspillite is Banded and Glassy and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Jaspillite vs Felsite. The hardness of Jaspillite is 3 and that of Felsite is 5-5.5. The types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type whereas types of Felsite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jaspillite and Felsite is white. The specific heat capacity of Jaspillite is 3.20 kJ/Kg K and that of Felsite 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.Jaspillite is heat resistant, impact resistant, wear resistant whereas Felsite is heat resistant, impact resistant.
