Definition
Trondhjemite is a leucocratic (light-colored) intrusive igneous rock. It is a variety of tonalite in which the plagioclase is mostly in the form of oligoclase. Trondhjemites are sometimes known as plagiogranites.
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite

Formation
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.

More about Trondhjemite and Hawaiite
Here you can know more about Trondhjemite and Hawaiite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Trondhjemite and Hawaiite consists of mineral content and compound content. The mineral content of Trondhjemite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Hawaiite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Trondhjemite vs Hawaiite, the texture, color and appearance plays an important role in determining the type of rock. Trondhjemite is available in black, brown, light to dark grey, white colors whereas, Hawaiite is available in black, brown, light to dark grey colors. Appearance of Trondhjemite is Banded and Foilated and that of Hawaiite is Dull and Soft. Properties of rock is another aspect for Trondhjemite vs Hawaiite. The hardness of Trondhjemite is 6-7 and that of Hawaiite is 6. The types of Trondhjemite are Intermediate intrusive rock whereas types of Hawaiite are Volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Trondhjemite is bluish black while that of Hawaiite is . The specific heat capacity of Trondhjemite is 0.92 kJ/Kg K and that of Hawaiite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Trondhjemite is heat resistant, pressure resistant, wear resistant whereas Hawaiite is heat resistant, pressure resistant, wear resistant.
