Definition
Jaspillite is an iron rich chemically formed rock which is common in banded iron formation rocks
Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate

Archaeological Significance
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.
An argillite is a fine-grained sedimentary rock mainly composed of clay particles which forms from lithified muds which contain variable amounts of silt-sized particles.

Jaspillite vs Argillite 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 Argillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Jaspillite and Properties of Argillite. Learn more about Jaspillite vs Argillite in the next section. The interior uses of Jaspillite include Decorative aggregates and Interior decoration whereas the interior uses of Argillite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Jaspillite and Argillite, 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 Argillite include Used for flooring, stair treads, borders and window sills..
More about Jaspillite and Argillite
Here you can know more about Jaspillite and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jaspillite and Argillite consists of mineral content and compound content. The mineral content of Jaspillite includes Coesite, Quartz, Sand and mineral content of Argillite includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Jaspillite vs Argillite, the texture, color and appearance plays an important role in determining the type of rock. Jaspillite is available in red, reddish brown colors whereas, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Jaspillite is Banded and Glassy and that of Argillite is Rough and Dull. Properties of rock is another aspect for Jaspillite vs Argillite. The hardness of Jaspillite is 3 and that of Argillite is 2-3. The types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type whereas types of Argillite are Metamorphic rock. 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 Argillite is white to grey. The specific heat capacity of Jaspillite is 3.20 kJ/Kg K and that of Argillite is 0.87 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 Argillite is heat resistant, impact resistant.
