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 Granophyre
Here you can know more about Pantellerite and Granophyre. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pantellerite and Granophyre consists of mineral content and compound content. The mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite and mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Pantellerite vs Granophyre, the texture, color and appearance plays an important role in determining the type of rock. Pantellerite is available in dark greenish - grey colors whereas, Granophyre is available in black, grey, orange, pink, white colors. Appearance of Pantellerite is Layered and Foliated and that of Granophyre is Veined or Pebbled. Properties of rock is another aspect for Pantellerite vs Granophyre. Hardness of Pantellerite and Granophyre is 6-7. The types of Pantellerite are Pantelleritic Ignimbrite whereas types of Granophyre are Intermediate intrusive rock. 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 Granophyre is white. The specific heat capacity of Pantellerite is 0.84 kJ/Kg K and that of Granophyre is 0.79 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 Granophyre is heat resistant, wear resistant.
