Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Websterite is ultramafic and ultrabasic rock that consists of roughly equal proportions of orthopyroxene and clinopyroxene. It is a special type of pyroxenite.

Archaeological Significance
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.
Websterite can be formed as cumulates in ultramafic intrusions by accumulation of pyroxene crystals at the base of the lava chamber.

All about Suevite and Websterite Properties
Know all about Suevite and Websterite properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Websterite belongs to Igneous Rocks.Texture of Suevite is Earthy whereas that of Websterite is Clastic, Granular, Phaneritic, Porphyritic. Suevite appears Banded and Websterite appears Layered, Banded, Veined and Shiny. The luster of Suevite is earthy while that of Websterite is dull to vitreous to submetallic. Suevite is available in black, brown, green, grey, pink colors whereas Websterite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Websterite are cemetery markers, commemorative tablets, creating artwork, laboratory bench tops, jewelry, sea defence, tombstones.
