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.

More about Pantellerite and Hornblendite
Here you can know more about Pantellerite and Hornblendite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pantellerite and Hornblendite consists of mineral content and compound content. The mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite and mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite. You can also check out the list of all Igneous Rocks. When we have to compare Pantellerite vs Hornblendite, the texture, color and appearance plays an important role in determining the type of rock. Pantellerite is available in dark greenish - grey colors whereas, Hornblendite is available in black, brown, green, grey colors. Appearance of Pantellerite is Layered and Foliated and that of Hornblendite is Foliated. Properties of rock is another aspect for Pantellerite vs Hornblendite. Hardness of Pantellerite and Hornblendite is 6-7. The types of Pantellerite are Pantelleritic Ignimbrite whereas types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite. 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 Hornblendite is white to grey. The specific heat capacity of Pantellerite is 0.84 kJ/Kg K and that of Hornblendite is 0.84 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 Hornblendite is heat resistant, pressure resistant, wear resistant.
