5 Formation

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.

Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.

Pumice vs Ignimbrite 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 Ignimbrite Reserves. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows. 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 Ignimbrite information and Pumice vs Ignimbrite characteristics in the upcoming sections.

More about Pumice and Ignimbrite

Here you can know more about Pumice and Ignimbrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pumice and Ignimbrite consists of mineral content and compound content. The mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica and mineral content of Ignimbrite includes Apatite, Biotite, Calcite, Chlorite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Pumice vs Ignimbrite, 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, Ignimbrite is available in beige, black, brown, grey, pink, white colors. Appearance of Pumice is Vesicular and that of Ignimbrite is Dull, Vesicular and Foilated. Properties of rock is another aspect for Pumice vs Ignimbrite. The hardness of Pumice is 6 and that of Ignimbrite is 4-6. The types of Pumice are Scoria whereas types of Ignimbrite 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 Ignimbrite is white, greenish white or grey. The specific heat capacity of Pumice is 0.87 kJ/Kg K and that of Ignimbrite is 0.20 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 Ignimbrite is heat resistant, impact resistant, pressure resistant, wear resistant.
