Definition
Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.
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 Anthracite and Suevite Properties
Know all about Anthracite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Anthracite and Suevite belong to Metamorphic Rocks.Texture of Anthracite is Amorphous, Glassy whereas that of Suevite is Earthy. Anthracite appears Veined or Pebbled and Suevite appears Banded. The luster of Anthracite is shiny while that of Suevite is earthy. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas Suevite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Anthracite are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
