Definition
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar
Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded

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.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

All about Diabase and Sandstone Properties
Know all about Diabase and Sandstone properties here. All properties of rocks are important as they define the type of rock and its application. Diabase belongs to Igneous Rocks while Sandstone belongs to Sedimentary Rocks.Texture of Diabase is Aphanitic, Granular whereas that of Sandstone is Clastic, Granular, Rough. Diabase appears Vesicular and Sandstone appears Rough. The luster of Diabase is while that of Sandstone is dull. Diabase is available in dark grey to black colors whereas Sandstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, 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 Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
