Archaeological Significance
Formation
Taconite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. When the river reaches a lake or sea, its load of transported rocks settles or deposits at the bottom of sea or lake.
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.

More about Taconite and Oolite
Here you can know more about Taconite and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Oolite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Oolite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Taconite vs Oolite. The hardness of Taconite is 5.5-6 and that of Oolite is 3-4. The types of Taconite are Iron formation whereas types of Oolite are Pisolitic Oolite and Oncolitic Oolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Taconite and Oolite is white. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Oolite is 0.65 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Taconite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Oolite is heat resistant, wear resistant.
