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
Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities

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.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

More about Metapelite and Scoria
Here you can know more about Metapelite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Scoria consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Scoria, 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, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Metapelite is Banded and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Metapelite vs Scoria. Hardness of Metapelite and Scoria is 5-6. The types of Metapelite are Not Available whereas types of Scoria are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface.
