Definition
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism

Formation
Pantellerite 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.
Slate is a low grade metamorphic rock that is generally formed by metamorphosis of mudstone or shale, under relatively low pressure and temperature conditions.

All about Pantellerite and Slate Properties
Know all about Pantellerite and Slate properties here. All properties of rocks are important as they define the type of rock and its application. Pantellerite belongs to Igneous Rocks while Slate belongs to Metamorphic Rocks.Texture of Pantellerite is Eutaxitic whereas that of Slate is Foliated. Pantellerite appears Layered and Foliated and Slate appears Dull. The luster of Pantellerite is earthy while that of Slate is dull. Pantellerite is available in dark greenish - grey colors whereas Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue colors. The commercial uses of Pantellerite are creating artwork and that of Slate are blackboards, commemorative tablets, laboratory bench tops, standard material for the bed of billiard table, standard material for the beds of pool and snooker table, tombstones, used in aquariums, writing slates.
