Archaeological Significance
Formation
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

Aplite vs Pumice 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. Aplite vs Pumice characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Pumice. Learn more about Aplite vs Pumice in the next section. The interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Pumice include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Aplite and Pumice, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Pumice include As dimension stone, Cement manufacture, For road aggregate, In landscaping and horticulture, Making natural cement, Production of lightweight concrete blocks.
More about Aplite and Pumice
Here you can know more about Aplite and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Pumice consists of mineral content and compound content. The mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz 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 Aplite vs Pumice, the texture, color and appearance plays an important role in determining the type of rock. Aplite is available in black, grey, orange, pink, white colors whereas, Pumice is available in beige, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Aplite is Veined or Pebbled and that of Pumice is Vesicular. Properties of rock is another aspect for Aplite vs Pumice. The hardness of Aplite is 6.5 and that of Pumice is 6. The types of Aplite are Igneous rock whereas types of Pumice are Scoria. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite is white while that of Pumice is white, greenish white or grey. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Pumice is 0.87 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Aplite is heat resistant, wear resistant whereas Pumice is impact resistant, pressure resistant.
