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.
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

Pantellerite vs Dacite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Pantellerite vs Dacite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pantellerite and Properties of Dacite. Learn more about Pantellerite vs Dacite in the next section. The interior uses of Pantellerite include Not yet used whereas the interior uses of Dacite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Pantellerite and Dacite, they have various applications in construction industry. The uses of Pantellerite in construction industry include Na and that of Dacite include As dimension stone, Construction aggregate, For road aggregate, Landscaping.
More about Pantellerite and Dacite
Here you can know more about Pantellerite and Dacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pantellerite and Dacite consists of mineral content and compound content. The mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite and mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Pantellerite vs Dacite, the texture, color and appearance plays an important role in determining the type of rock. Pantellerite is available in dark greenish - grey colors whereas, Dacite is available in bluish - grey, brown, grey, light to dark grey colors. Appearance of Pantellerite is Layered and Foliated and that of Dacite is Vesicular. Properties of rock is another aspect for Pantellerite vs Dacite. The hardness of Pantellerite is 6-7 and that of Dacite is 2-2.25. The types of Pantellerite are Pantelleritic Ignimbrite whereas types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pantellerite is unknown while that of Dacite is white. The specific heat capacity of Pantellerite is Not Available and that of Dacite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Pantellerite is heat resistant whereas Dacite is heat resistant, impact resistant, pressure resistant, wear resistant.
