Definition
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite
Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.

Archaeological Significance
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.
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.

More about Pantellerite and Gossan
Here you can know more about Pantellerite and Gossan. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pantellerite and Gossan consists of mineral content and compound content. The mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite and mineral content of Gossan includes Apatite, Augite, Biotite, Bronzite, Calcite, Chert, Epidote, Feldspar, Hornblende, Micas, Plagioclase, Pyroxene, Quartz, Sulfides, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Pantellerite vs Gossan, the texture, color and appearance plays an important role in determining the type of rock. Pantellerite is available in dark greenish - grey colors whereas, Gossan is available in brown, brown- black, gold, green, rust colors. Appearance of Pantellerite is Layered and Foliated and that of Gossan is Dull and Banded. Properties of rock is another aspect for Pantellerite vs Gossan. The hardness of Pantellerite is 6-7 and that of Gossan is 4-5. The types of Pantellerite are Pantelleritic Ignimbrite whereas types of Gossan are Translocated gossan and Leakage gossan. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pantellerite is while that of Gossan is white to grey. The specific heat capacity of Pantellerite is 0.84 kJ/Kg K and that of Gossan is 0.24 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 Gossan is heat resistant, impact resistant, pressure resistant.
