Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
An iron rich extrusive rock found as a member of the alkali basalt magma series
Origin
Italy
Isle of Mull, Scotland

Etymology
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
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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