Definition
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Archaeological Significance
Formation
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

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