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.
Latite 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 Latite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Pumice vs Latite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pumice and Properties of Latite. Learn more about Pumice vs Latite in the next section. The interior uses of Pumice include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Latite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Pumice and Latite, they have various applications in construction industry. The uses of Pumice in construction industry include As dimension stone, Cement manufacture, For road aggregate, In landscaping and horticulture, Making natural cement, Production of lightweight concrete blocks and that of Latite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Pumice and Latite
Here you can know more about Pumice and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pumice and Latite consists of mineral content and compound content. The mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica and mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Pumice vs Latite, 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, Latite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Pumice is Vesicular and that of Latite is Rough. Properties of rock is another aspect for Pumice vs Latite. The hardness of Pumice is 6 and that of Latite is 5-5.5. The types of Pumice are Scoria whereas types of Latite are Rhomb porphyries. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pumice and Latite is white, greenish white or grey. The specific heat capacity of Pumice is 0.87 kJ/Kg K and that of Latite is 0.92 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 Latite is heat resistant, pressure resistant.
