Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
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.

Formation
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.

More about Suevite and Trondhjemite
Here you can know more about Suevite and Trondhjemite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Suevite and Trondhjemite consists of mineral content and compound content. The mineral content of Suevite includes Coesite, Quartz, Stishovite and mineral content of Trondhjemite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all . When we have to compare Suevite vs Trondhjemite, the texture, color and appearance plays an important role in determining the type of rock. Suevite is available in black, brown, colourless, green, grey, pink colors whereas, Trondhjemite is available in black, brown, light to dark grey, white colors. Appearance of Suevite is Banded and that of Trondhjemite is Banded and Foilated. Properties of rock is another aspect for Suevite vs Trondhjemite. The hardness of Suevite is 5.5 and that of Trondhjemite is 6-7. The types of Suevite are Phyllosilicates, Calcite whereas types of Trondhjemite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Suevite is light to dark brown while that of Trondhjemite is bluish black. The specific heat capacity of Suevite is 0.92 kJ/Kg K and that of Trondhjemite 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.Suevite is heat resistant whereas Trondhjemite is heat resistant, pressure resistant, wear resistant.
