Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
  
Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth

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 Late Latin Basaltes (variant of basanites ), very hard stone, which was imported from Ancient Greek Basanites

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
  
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

All about Conglomerate and Basalt Properties
Know all about Conglomerate and Basalt properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Basalt belongs to Igneous Rocks.Texture of Conglomerate is Clastic whereas that of Basalt is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Conglomerate appears Shiny and Rounded and Basalt appears Dull and Soft. The luster of Conglomerate is dull while that of Basalt is not available. Conglomerate and Basalt 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 Basalt are an oil and gas reservoir, commemorative tablets, creating artwork, used in aquariums.
