Pantellerite and Siltstone


Definition

Definition
Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt   
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

Formation

Formation
Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.   
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 Siltstone and Pantellerite Properties

Know all about Siltstone and Pantellerite properties here. All properties of rocks are important as they define the type of rock and its application. Siltstone belongs to Sedimentary Rocks while Pantellerite belongs to Igneous Rocks.Texture of Siltstone is Clastic whereas that of Pantellerite is Eutaxitic. Siltstone appears Rough and Pantellerite appears Layered and Foliated. The luster of Siltstone is dull while that of Pantellerite is earthy. Siltstone is available in brown, red, reddish brown colors whereas Pantellerite is available in dark greenish - grey colors. The commercial uses of Siltstone are raw material for the manufacture of mortar, soil conditioner and that of Pantellerite are creating artwork.
