5 Formation

5.1 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.

Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

All about Diabase and Diatomite Properties

Know all about Diabase and Diatomite properties here. All properties of rocks are important as they define the type of rock and its application. Diabase belongs to Igneous Rocks while Diatomite belongs to Sedimentary Rocks.Texture of Diabase is Aphanitic, Granular whereas that of Diatomite is Clastic or Non-Clastic. Diabase appears Vesicular and Diatomite appears Soft. The luster of Diabase is not available while that of Diatomite is dull. Diabase is available in dark grey to black colors whereas Diatomite is available in grey, 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 Diatomite are alumina refineries, animal feed filler, as a feed additive for livestock, creating artwork, drawing on blackboards, fire resistant, gymnasts, athletes and mountain climbers use for grip, in aquifers, soil conditioner, to ignite fire, used as a filter medium, used as an insecticide, whiting material in toothpaste, paint and paper.
