5 Formation

5.1 Formation

Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

All about Siltstone and Basanite Properties

Know all about Siltstone and Basanite properties here. All properties of rocks are important as they define the type of rock and its application. Siltstone belongs to Sedimentary Rocks while Basanite belongs to Igneous Rocks.Texture of Siltstone is Clastic whereas that of Basanite is Aphanitic to Porphyritic. Siltstone appears Rough and Basanite appears Glassy or Pearly. The luster of Siltstone is dull while that of Basanite is waxy and dull. Siltstone is available in brown, red, reddish brown colors whereas Basanite is available in black, brown, green, grey, red, white colors. The commercial uses of Siltstone are raw material for the manufacture of mortar, soil conditioner and that of Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms.
