Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

More about Hawaiite and Peridotite
Here you can know more about Hawaiite and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hawaiite and Peridotite consists of mineral content and compound content. The mineral content of Hawaiite includes Olivine, Plagioclase, Pyroxene and mineral content of Peridotite 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 Peridotite, 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, Peridotite is available in dark greenish - grey colors. Appearance of Hawaiite is Dull and Soft and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Hawaiite vs Peridotite. The hardness of Hawaiite is 6 and that of Peridotite is 5.5-6. The types of Hawaiite are Not Available whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. 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 Peridotite is white. The specific heat capacity of Hawaiite is Not Available and that of Peridotite is 1.26 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 Peridotite is heat resistant, pressure resistant, wear resistant.
