Formation
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.
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.

All about Pyroxenite and Wackestone Properties
Know all about Pyroxenite and Wackestone properties here. All properties of rocks are important as they define the type of rock and its application. Pyroxenite belongs to Igneous Rocks while Wackestone belongs to Sedimentary Rocks.Texture of Pyroxenite is Clastic, Granular, Phaneritic, Porphyritic whereas that of Wackestone is Clastic. Pyroxenite appears Layered, Banded, Veined and Shiny and Wackestone appears Rough and Dull. The luster of Pyroxenite is dull to vitreous to submetallic while that of Wackestone is dull. Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors whereas Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. The commercial uses of Pyroxenite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones and that of Wackestone are cemetery markers, pottery.
