5.1 Formation

Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

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

Minette vs Pumice 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 Minette and Pumice Reserves. Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. 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 Minette vs Pumice information and Minette vs Pumice characteristics in the upcoming sections.

More about Minette and Pumice

Here you can know more about Minette and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Minette and Pumice consists of mineral content and compound content. The mineral content of Minette includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Minette vs Pumice, the texture, color and appearance plays an important role in determining the type of rock. Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Minette is Dull, Banded and Foilated and that of Pumice is Vesicular. Properties of rock is another aspect for Minette vs Pumice. The hardness of Minette is 5-6 and that of Pumice is 6. The types of Minette are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Pumice are Scoria.
