Definition
Aplite is a fine-grained granite composed mainly of feldspar and quartz
Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows

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

Aplite vs Ignimbrite 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 Ignimbrite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Ignimbrite. Learn more about Aplite vs Ignimbrite 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 Ignimbrite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Aplite and Ignimbrite, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Ignimbrite include Building houses or walls, Construction aggregate.
More about Aplite and Ignimbrite
Here you can know more about Aplite and Ignimbrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Ignimbrite 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 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 Aplite vs Ignimbrite, 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, Ignimbrite is available in beige, black, brown, grey, pink, white colors. Appearance of Aplite is Veined or Pebbled and that of Ignimbrite is Dull, Vesicular and Foilated. Properties of rock is another aspect for Aplite vs Ignimbrite. The hardness of Aplite is 6.5 and that of Ignimbrite is 4-6. The types of Aplite are Not Available 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 Aplite and Ignimbrite is white. The specific heat capacity of Aplite is 0.79 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.Aplite is heat resistant, wear resistant whereas Ignimbrite is heat resistant, impact resistant, pressure resistant, wear resistant.
