Definition
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals

Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

More about Hawaiite and Syenite
Here you can know more about Hawaiite and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hawaiite and Syenite consists of mineral content and compound content. The mineral content of Hawaiite includes Olivine, Plagioclase, Pyroxene and mineral content of Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Hawaiite vs Syenite, 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, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Hawaiite is Dull and Soft and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Hawaiite vs Syenite. The hardness of Hawaiite is 6 and that of Syenite is 5.5-6. The types of Hawaiite are Not Available whereas types of Syenite are Shonkinite. 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 Syenite is white. The specific heat capacity of Hawaiite is Not Available and that of Syenite is 0.92 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 Syenite is heat resistant, impact resistant, wear resistant.
