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

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.

All about Diamictite and Novaculite Properties
Know all about Diamictite and Novaculite properties here. All properties of rocks are important as they define the type of rock and its application. Diamictite and Novaculite belong to Sedimentary Rocks.Texture of Diamictite is Clastic whereas that of Novaculite is Banded, Glassy, Rough, Vitreous. Diamictite appears Banded and Novaculite appears Glassy or Pearly. The luster of Diamictite is grainy, pearly and vitreous while that of Novaculite is waxy and dull. Diamictite is available in brown, buff colors whereas Novaculite is available in black, brown, green, grey, red, white colors. The commercial uses of Diamictite are commemorative tablets, creating artwork, production of lime and that of Novaculite are cemetery markers, gemstone, in aquifers, in fire-starting tools, jewelry, manufacture of tools, pebbles are used in ball mills to grind in ceramics industry, to determine the gold content of jewelry.
