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
Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals

Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

All about Hyaloclastite and Pumice Properties
Know all about Hyaloclastite and Pumice properties here. All properties of rocks are important as they define the type of rock and its application. Hyaloclastite and Pumice belong to Igneous Rocks.Texture of Hyaloclastite is Pyroclastic whereas that of Pumice is Vesicular. Hyaloclastite appears Dull and Pumice appears Vesicular. The luster of Hyaloclastite is dull and grainy while that of Pumice is earthy. Hyaloclastite is available in brown, grey, yellow colors whereas Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. The commercial uses of Hyaloclastite are cemetery markers, creating artwork and that of Pumice are as a traction material on snow-covered roads, as an abrasive in pencil erasers, fine abrasive used for polishing, manufacture of soap, solvents, dyes, plastics and fibres, used in aquariums.
