5.1 Formation

Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

Wehrlite 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.

Pumice vs Wehrlite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Pumice and Wehrlite Reserves. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Pumice vs Wehrlite information and Pumice vs Wehrlite characteristics in the upcoming sections.

More about Pumice and Wehrlite

Here you can know more about Pumice and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pumice and Wehrlite consists of mineral content and compound content. The mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Pumice vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Pumice is Vesicular and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Pumice vs Wehrlite. The hardness of Pumice is 6 and that of Wehrlite is 5.5-6. The types of Pumice are Scoria whereas types of Wehrlite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pumice and Wehrlite is white, greenish white or grey. The specific heat capacity of Pumice is 0.87 kJ/Kg K and that of Wehrlite is 0.63 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Pumice is impact resistant, pressure resistant whereas Wehrlite is heat resistant, impact resistant, pressure resistant.
