Formation

Formation
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.   
Monzonite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Pumice and Monzonite Properties

Know all about Pumice and Monzonite properties here. All properties of rocks are important as they define the type of rock and its application. Pumice and Monzonite belong to Igneous Rocks.Texture of Pumice is Vesicular whereas that of Monzonite is Phaneritic. Pumice appears Vesicular and Monzonite appears Shiny. The luster of Pumice is earthy while that of Monzonite is subvitreous to dull. Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors whereas Monzonite is available in black, brown, light to dark grey, white colors. The commercial uses 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 and that of Monzonite are creating artwork.
