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.
  
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.

More about Oolite and Taconite
Here you can know more about Oolite and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Taconite consists of mineral content and compound content. The mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Taconite includes Hematite, Magnetite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Oolite vs Taconite, 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, Taconite is available in red, reddish brown colors. Appearance of Oolite is Rounded and Rough and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Oolite vs Taconite. The hardness of Oolite is 3-4 and that of Taconite is 5.5-6. The types of Oolite are Not Available whereas types of Taconite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oolite and Taconite is white.
