Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Novaculite is a dense, hard, fine-grained, siliceous metamorpic rock which is a type of chert that breaks with conchoidal fracture

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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 Conglomerate and Novaculite Properties
Know all about Conglomerate and Novaculite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate and Novaculite belong to Sedimentary Rocks.Texture of Conglomerate is Clastic whereas that of Novaculite is Banded, Glassy, Rough, Vitreous. Conglomerate appears Shiny and Rounded and Novaculite appears Glassy or Pearly. The luster of Conglomerate is dull while that of Novaculite is waxy and dull. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Novaculite is available in black, brown, green, grey, red, white colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones 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.
