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

Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
  
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

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