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
Novaculite is a dense, hard, fine-grained, siliceous metamorpic rock which is a type of chert that breaks with conchoidal fracture

Features
Host Rock for Lead, Is one of the oldest rock
Clasts are smooth to touch, Easily splits into thin plates, Has High structural resistance against erosion and climate
Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Novaculite forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The formation of Novaculite can be either of chemical or biological origin.

More about Diamictite and Novaculite
Here you can know more about Diamictite and Novaculite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Novaculite consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Novaculite includes Quartz, Silicon. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Novaculite, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Novaculite is available in black, brown, green, grey, red, white colors. Appearance of Diamictite is Banded and that of Novaculite is Glassy or Pearly. Properties of rock is another aspect for Diamictite vs Novaculite. The hardness of Diamictite is 2-3 and that of Novaculite is 7. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Novaculite are Sedimentary rock. 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 Novaculite is . The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Novaculite is 0.74 kJ/Kg K.
