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

Formation
Formation
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.
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 Suevite and Diabase Properties
Know all about Suevite and Diabase properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Diabase belongs to Igneous Rocks.Texture of Suevite is Earthy whereas that of Diabase is Aphanitic, Granular. Suevite appears Banded and Diabase appears Vesicular. The luster of Suevite is earthy while that of Diabase is not available. Suevite is available in black, brown, colourless, green, grey, pink colors whereas Diabase is available in dark grey to black colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Diabase are an oil and gas reservoir, cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
