Diabase and Suevite
Definition
Definition
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Diabase and Suevite Properties
Know all about Diabase and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Diabase belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Diabase is Aphanitic, Granular whereas that of Suevite is Earthy. Diabase appears Vesicular and Suevite appears Banded. The luster of Diabase is not available while that of Suevite is earthy. Diabase is available in dark grey to black colors whereas Suevite is available in black, brown, colourless, green, grey, pink 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 Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
