Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Archaeological Significance
Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
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 Claystone and Suevite Properties
Know all about Claystone and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Claystone belongs to Sedimentary Rocks while Suevite belongs to Metamorphic Rocks.Texture of Claystone is Clastic whereas that of Suevite is Earthy. Claystone appears Rough and Dull and Suevite appears Banded. The luster of Claystone is dull while that of Suevite is earthy. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Suevite is available in black, brown, green, grey, pink colors. The commercial uses of Claystone are pottery and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
