5 Formation

5.1 Formation

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.

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.

All about Arkose and Pantellerite Properties

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