Definition
Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

All about Pumice and Marble Properties
Know all about Pumice and Marble properties here. All properties of rocks are important as they define the type of rock and its application. Pumice belongs to Igneous Rocks while Marble belongs to Metamorphic Rocks.Texture of Pumice is Vesicular whereas that of Marble is Granular. Pumice appears Vesicular and Marble appears Veined and Shiny. The luster of Pumice is earthy while that of Marble is dull to pearly to subvitreous. Pumice is available in beige, grey, light green, light grey, pink, white, yellow- grey colors whereas Marble is available in black, blue, brown, grey, pink, 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 Marble are cemetery markers, commemorative tablets, creating artwork, curling, laboratory bench tops, paper industry, tombstones, used in aquariums, whiting material in toothpaste, paint and paper.
