Definition
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite
Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt

Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
Pyrolite 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.

Hawaiite vs Pyrolite 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. Hawaiite vs Pyrolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hawaiite and Properties of Pyrolite. Learn more about Hawaiite vs Pyrolite in the next section. The interior uses of Hawaiite include Decorative aggregates, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Kitchens whereas the interior uses of Pyrolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Hawaiite and Pyrolite, they have various applications in construction industry. The uses of Hawaiite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Pyrolite include As dimension stone, Cobblestones.
More about Hawaiite and Pyrolite
Here you can know more about Hawaiite and Pyrolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hawaiite and Pyrolite consists of mineral content and compound content. The mineral content of Hawaiite includes Olivine, Plagioclase, Pyroxene and mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Hawaiite vs Pyrolite, the texture, color and appearance plays an important role in determining the type of rock. Hawaiite is available in black, brown, light to dark grey colors whereas, Pyrolite is available in dark greenish - grey colors. Appearance of Hawaiite is Dull and Soft and that of Pyrolite is Rough and Shiny. Properties of rock is another aspect for Hawaiite vs Pyrolite. The hardness of Hawaiite is 6 and that of Pyrolite is 5.5-6. The types of Hawaiite are Not Available whereas types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hawaiite is not available while that of Pyrolite is white. The specific heat capacity of Hawaiite is Not Available and that of Pyrolite is 1.25 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Hawaiite is heat resistant, pressure resistant, wear resistant whereas Pyrolite is heat resistant, pressure resistant, wear resistant.
