Definition
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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 Metapelite and Oolite
Here you can know more about Metapelite and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Oolite consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Oolite, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Metapelite is Banded and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Metapelite vs Oolite. The hardness of Metapelite is 5-6 and that of Oolite is 3-4. The types of Metapelite are Not Available whereas types of Oolite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface.
