Definition
Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

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.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

All about Pumice and Diamictite Properties
Know all about Pumice and Diamictite properties here. All properties of rocks are important as they define the type of rock and its application. Pumice belongs to Igneous Rocks while Diamictite belongs to Sedimentary Rocks.Texture of Pumice is Vesicular whereas that of Diamictite is Clastic. Pumice appears Vesicular and Diamictite appears Banded. The luster of Pumice is earthy while that of Diamictite is grainy, pearly and vitreous. Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors whereas Diamictite is available in brown, buff 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 Diamictite are commemorative tablets, creating artwork, production of lime.
