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

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

More about Novaculite and Diamictite
Here you can know more about Novaculite and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Novaculite and Diamictite consists of mineral content and compound content. The mineral content of Novaculite includes Quartz, Silicon and mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Novaculite vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Novaculite is available in black, brown, green, grey, red, white colors whereas, Diamictite is available in brown, buff colors. Appearance of Novaculite is Glassy or Pearly and that of Diamictite is Banded. Properties of rock is another aspect for Novaculite vs Diamictite. The hardness of Novaculite is 7 and that of Diamictite is 2-3. The types of Novaculite are Not Available whereas types of Diamictite are Bedded Diamictite and Laminated Diamictite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Novaculite is colorless while that of Diamictite is light to dark brown. The specific heat capacity of Novaculite is 0.74 kJ/Kg K and that of Diamictite is 0.75 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Novaculite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Diamictite is heat resistant, impact resistant.
