Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

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