5 Formation

5.1 Formation

Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

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 Chalk and Pantellerite

Here you can know more about Chalk and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Pantellerite consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite. You can also check out the list of all Sedimentary Rocks. When we have to compare Chalk vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Chalk is Soft and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Chalk vs Pantellerite. The hardness of Chalk is 1 and that of Pantellerite is 6-7. The types of Chalk are Not Available whereas types of Pantellerite are Pantelleritic Ignimbrite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk is white while that of Pantellerite is unknown. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Pantellerite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Chalk is heat resistant whereas Pantellerite is heat resistant.
