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
From Pelos or clay in Greek
Durable Rock, Medium Hardness Rock
Coarse Grained Rock, Fine Grained Rock, Medium Grained Rock, Opaque Rock
Dark Greenish - Grey, Green, Light Green, Light Greenish Grey
Decorative Aggregates, Interior Decoration
As Building Stone, As Facing Stone
Cement Manufacture, Construction Aggregate, for Road Aggregate
Commemorative Tablets, Creating Artwork
Easily splits into thin plates, It is One of the Oldest, Strongest and Hardest Rock
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.
