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
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Features
Easily splits into thin plates, It is One of the Oldest, Strongest and Hardest Rock
Clasts are smooth to touch, Easily splits into thin plates, Has High structural resistance against erosion and climate
Archaeological Significance
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.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

More about Metapelite and Flint
Here you can know more about Metapelite and Flint. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Flint consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Flint includes Silicon. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Flint, 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, Flint is available in black, brown, green, grey, red, white colors. Appearance of Metapelite is Banded and that of Flint is Glassy or Pearly. Properties of rock is another aspect for Metapelite vs Flint. The hardness of Metapelite is 5-6 and that of Flint is 7. The types of Metapelite are Metamorphic rock whereas types of Flint are Chert and Jasper. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Metapelite is while that of Flint is white. The specific heat capacity of Metapelite is 0.72 kJ/Kg K and that of Flint is 0.74 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Metapelite is heat resistant, impact resistant, pressure resistant whereas Flint is heat resistant, impact resistant, pressure resistant, wear resistant.
