Conglomerate and Novaculite


Definition

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

Formation

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.   
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Novaculite and Conglomerate Properties

Know all about Novaculite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Novaculite and Conglomerate belong to Sedimentary Rocks.Texture of Novaculite is Banded, Glassy, Rough, Vitreous whereas that of Conglomerate is Clastic. Novaculite appears Glassy or Pearly and Conglomerate appears Shiny and Rounded. The luster of Novaculite is waxy and dull while that of Conglomerate is dull. Novaculite is available in black, brown, green, grey, red, white colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses 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 and that of Conglomerate are cemetery markers, in aquifers, tombstones.
