Archaeological Significance
Formation
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

The uses of Oolite in construction industry include Cement manufacture, Cobblestones, Landscaping and that of Jaspillite 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.
More about Oolite and Jaspillite
Here you can know more about Oolite and Jaspillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Jaspillite consists of mineral content and compound content. The mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Jaspillite includes Coesite, Quartz, Sand. You can also check out the list of all Sedimentary Rocks. When we have to compare Oolite vs Jaspillite, the texture, color and appearance plays an important role in determining the type of rock. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas, Jaspillite is available in red, reddish brown colors. Appearance of Oolite is Rounded and Rough and that of Jaspillite is Banded and Glassy. Properties of rock is another aspect for Oolite vs Jaspillite. The hardness of Oolite is 3-4 and that of Jaspillite is 3. The types of Oolite are Pisolitic Oolite and Oncolitic Oolite whereas types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type.
