Definition
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite

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

More about Hawaiite and Foidolite
Here you can know more about Hawaiite and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hawaiite and Foidolite consists of mineral content and compound content. The mineral content of Hawaiite includes Olivine, Plagioclase, Pyroxene and mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Hawaiite vs Foidolite, 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, Foidolite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Hawaiite is Dull and Soft and that of Foidolite is Dull. Properties of rock is another aspect for Hawaiite vs Foidolite. The hardness of Hawaiite is 6 and that of Foidolite is 1.5. The types of Hawaiite are Not Available whereas types of Foidolite are Not Available. 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 Foidolite is white. The specific heat capacity of Hawaiite is Not Available and that of Foidolite is Not Available. 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 Foidolite is heat resistant, wear resistant.
