Definition
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone
Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster

Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
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.

More about Diamictite and Anthracite
Here you can know more about Diamictite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Anthracite consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Diamictite is Banded and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Diamictite vs Anthracite. The hardness of Diamictite is 2-3 and that of Anthracite is 1-1.5. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Anthracite are Semi-anthracite and Meta-anthracite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diamictite is light to dark brown while that of Anthracite is black. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Anthracite is 1.32 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diamictite is heat resistant, impact resistant whereas Anthracite is heat resistant, water resistant.
