Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture

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.
Chert forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The chert formation can be either of chemical or biological origin.

All about Suevite and Chert Properties
Know all about Suevite and Chert properties here. All properties of rocks are important as they define the type of rock and its application. Suevite belongs to Metamorphic Rocks while Chert belongs to Sedimentary Rocks.Texture of Suevite is Earthy whereas that of Chert is Banded, Rough. Suevite appears Banded and Chert appears Glassy or Pearly. The luster of Suevite is earthy while that of Chert is waxy and dull. Suevite is available in black, brown, green, grey, pink colors whereas Chert is available in black, brown, green, grey, red, white colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Chert are creating artwork, gemstone, in fire-starting tools, jewelry, to ignite fire, used in flintlock firearms.
