Definition
Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Etymology
From early 19th century coined in French, formed irregularly from Greek diorizein distinguish
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

Archaeological Significance
Formation
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Diorite and Conglomerate Properties
Know all about Diorite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Diorite belongs to Igneous Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Diorite is Phaneritic whereas that of Conglomerate is Clastic. Diorite appears Shiny and Conglomerate appears Shiny and Rounded. The luster of Diorite is shiny while that of Conglomerate is dull. Diorite is available in black, brown, light to dark grey, white colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Diorite are creating artwork, curling and that of Conglomerate are cemetery markers, in aquifers, tombstones.
