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
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.

Features
Easily splits into thin plates, It is One of the Oldest, Strongest and Hardest Rock
Available in Lots of Colors and Patterns, Generally rough to touch, Very fine grained rock
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.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

More about Metapelite and Ganister
Here you can know more about Metapelite and Ganister. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Ganister consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Ganister, 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, Ganister is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Metapelite is Banded and that of Ganister is Rough. Properties of rock is another aspect for Metapelite vs Ganister. The hardness of Metapelite is 5-6 and that of Ganister is 6-7. The types of Metapelite are Metamorphic rock whereas types of Ganister are Siliceous rock. 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 Ganister is white. The specific heat capacity of Metapelite is 0.72 kJ/Kg K and that of Ganister is 0.92 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 Ganister is heat resistant, impact resistant, pressure resistant.
