5 Formation

5.1 Formation

Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

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 Arkose and Diabase Properties

Know all about Arkose and Diabase properties here. All properties of rocks are important as they define the type of rock and its application. Arkose belongs to Sedimentary Rocks while Diabase belongs to Igneous Rocks.Texture of Arkose is Clastic whereas that of Diabase is Aphanitic, Granular. Arkose appears Rough and Dull and Diabase appears Vesicular. The luster of Arkose is dull while that of Diabase is not available. Arkose is available in reddish brown colors whereas Diabase is available in dark grey to black colors. The commercial uses of Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones and that of Diabase are an oil and gas reservoir, cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
