16 Formation
16.1 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.
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

All about Diabase and Jasperoid Properties

Know all about Diabase and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Diabase belongs to Igneous Rocks while Jasperoid belongs to Sedimentary Rocks.Texture of Diabase is Aphanitic, Granular whereas that of Jasperoid is Earthy. Diabase appears Vesicular and Jasperoid appears Glassy or Pearly. The luster of Diabase is not available while that of Jasperoid is vitreous and pearly. Diabase is available in dark grey to black colors whereas Jasperoid is available in black, brown, colourless, green, grey, pink, white 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 Jasperoid are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
