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.
  
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

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