Definition

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

Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

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 French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock

Formation

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

Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

All about Conglomerate and Dolomite Properties

Know all about Conglomerate and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate and Dolomite belong to Sedimentary Rocks.Texture of Conglomerate is Clastic whereas that of Dolomite is Earthy. Conglomerate appears Shiny and Rounded and Dolomite appears Glassy or Pearly. The luster of Conglomerate is dull while that of Dolomite is vitreous and pearly. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Dolomite is available in black, brown, green, grey, pink, white colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Dolomite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
