Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment

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

All about Basanite and Hyaloclastite Properties
Know all about Basanite and Hyaloclastite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite and Hyaloclastite belong to Igneous Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Hyaloclastite is Pyroclastic. Basanite appears Glassy or Pearly and Hyaloclastite appears Dull. The luster of Basanite is waxy and dull while that of Hyaloclastite is dull and grainy. Basanite is available in black, brown, green, grey, red, white colors whereas Hyaloclastite is available in brown, grey, yellow colors. The commercial uses 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 and that of Hyaloclastite are cemetery markers, creating artwork.
