Definition

Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar

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

Formation

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.

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

All about Diabase and Conglomerate Properties

Know all about Diabase and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Diabase belongs to Igneous Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Diabase is Aphanitic, Granular whereas that of Conglomerate is Clastic. Diabase appears Vesicular and Conglomerate appears Shiny and Rounded. The luster of Diabase is while that of Conglomerate is dull. Diabase 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 Diabase are an oil and gas reservoir, cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones and that of Conglomerate are cemetery markers, in aquifers, tombstones.
