Definition
Jadeitite is a metamorphic rock usually found in blueschist grade metamorphic terrains
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.

Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.

More about Jadeitite and Trondhjemite
Here you can know more about Jadeitite and Trondhjemite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Trondhjemite consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides 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 Metamorphic Rocks. When we have to compare Jadeitite vs Trondhjemite, the texture, color and appearance plays an important role in determining the type of rock. Jadeitite is available in black, brown, green, grey, white colors whereas, Trondhjemite is available in black, brown, light to dark grey, white colors. Appearance of Jadeitite is Rough and Dull and that of Trondhjemite is Banded and Foilated. Properties of rock is another aspect for Jadeitite vs Trondhjemite. The hardness of Jadeitite is 3-5 and that of Trondhjemite is 6-7. The types of Jadeitite are Metamorphic rock whereas types of Trondhjemite are Intermediate intrusive rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jadeitite is white, greenish white or grey while that of Trondhjemite is bluish black. The specific heat capacity of Jadeitite is 0.95 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.Jadeitite is heat resistant, water resistant whereas Trondhjemite is heat resistant, pressure resistant, wear resistant.
