Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Etymology
From the Lherz Massif, an alpine peridotite complex, at Étang de Lers, near Massat in the French Pyrenees; Lherz is the archaic spelling of this location
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

Formation
Lherzolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Lherzolite and Conglomerate Properties
Know all about Lherzolite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite belongs to Igneous Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Lherzolite is Grenue whereas that of Conglomerate is Clastic. Lherzolite appears Glassy, Vesicular and Foilated and Conglomerate appears Shiny and Rounded. The luster of Lherzolite is subvitreous to dull while that of Conglomerate is dull. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums and that of Conglomerate are cemetery markers, in aquifers, tombstones.
