Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

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