Pantellerite and Arkose


Arkose and Pantellerite


Definition

Definition
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite   
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar

Etymology
From Pantelleria, a volcanic island in the Strait of Sicily   
From Auvergne region of France used by a French geologist Alexandre Brongniart in 1826 who applied this term to some feldspathic sandstones

Formation

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.   
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

All about Pantellerite and Arkose Properties

Know all about Pantellerite and Arkose properties here. All properties of rocks are important as they define the type of rock and its application. Pantellerite belongs to Igneous Rocks while Arkose belongs to Sedimentary Rocks.Texture of Pantellerite is Eutaxitic whereas that of Arkose is Clastic. Pantellerite appears Layered and Foliated and Arkose appears Rough and Dull. The luster of Pantellerite is earthy while that of Arkose is dull. Pantellerite is available in dark greenish - grey colors whereas Arkose is available in reddish brown colors. The commercial uses of Pantellerite are creating artwork and that of Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones.
