Definition
Marl is an unconsolidated sedimentary rock consisting of clay and lime
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Archaeological Significance
Formation
Marl forms when very fine-grained clay particles are deposited in water which settles at the bottom of water bodies and are compacted by overlying sediment; the water squeezes out and hence forming Marl rock.
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 Marl and Suevite Properties
Know all about Marl and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Marl belongs to Sedimentary Rocks while Suevite belongs to Metamorphic Rocks.Texture of Marl is Earthy whereas that of Suevite is Earthy. Marl appears Rough and Dull and Suevite appears Banded. The luster of Marl is dull while that of Suevite is earthy. Marl is available in beige, brown, green, grey, white colors whereas Suevite is available in black, brown, green, grey, pink colors. The commercial uses of Marl are creating artwork, soil conditioner and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
