Definition

Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions

Etymology

From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

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

Formation

Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

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.

All about Conglomerate and Lherzolite Properties

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