Definition
A carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud matrix.
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

Formation
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.
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.

All about Wackestone and Metapelite Properties
Know all about Wackestone and Metapelite properties here. All properties of rocks are important as they define the type of rock and its application. Wackestone belongs to Sedimentary Rocks while Metapelite belongs to Metamorphic Rocks.Texture of Wackestone is Clastic whereas that of Metapelite is Foliated. Wackestone appears Rough and Dull and Metapelite appears Banded. The luster of Wackestone is dull while that of Metapelite is earthy. Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. The commercial uses of Wackestone are cemetery markers, pottery and that of Metapelite are commemorative tablets, creating artwork.
