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.
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

Jaspillite vs Amphibolite 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 Amphibolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Jaspillite and Properties of Amphibolite. Learn more about Jaspillite vs Amphibolite in the next section. The interior uses of Jaspillite include Decorative aggregates and Interior decoration whereas the interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Jaspillite and Amphibolite, 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 Amphibolite include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone.
More about Jaspillite and Amphibolite
Here you can know more about Jaspillite and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jaspillite and Amphibolite consists of mineral content and compound content. The mineral content of Jaspillite includes Coesite, Quartz, Sand and mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite. You can also check out the list of all Sedimentary Rocks. When we have to compare Jaspillite vs Amphibolite, the texture, color and appearance plays an important role in determining the type of rock. Jaspillite is available in red, reddish brown colors whereas, Amphibolite is available in black, brown, green, grey colors. Appearance of Jaspillite is Banded and Glassy and that of Amphibolite is Foliated. Properties of rock is another aspect for Jaspillite vs Amphibolite. The hardness of Jaspillite is 3 and that of Amphibolite is 6-7. The types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type whereas types of Amphibolite are Hornblendite. 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 Amphibolite is white to grey. The specific heat capacity of Jaspillite is 3.20 kJ/Kg K and that of Amphibolite is 0.84 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 Amphibolite is heat resistant, pressure resistant, wear resistant.
