Definition
Jaspillite is an iron rich chemically formed rock which is common in banded iron formation rocks
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
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.

More about Jaspillite and Trondhjemite
Here you can know more about Jaspillite and Trondhjemite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jaspillite and Trondhjemite consists of mineral content and compound content. The mineral content of Jaspillite includes Coesite, Quartz, Sand 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 Sedimentary Rocks. When we have to compare Jaspillite vs Trondhjemite, the texture, color and appearance plays an important role in determining the type of rock. Jaspillite is available in red, reddish brown colors whereas, Trondhjemite is available in black, brown, light to dark grey, white colors. Appearance of Jaspillite is Banded and Glassy and that of Trondhjemite is Banded and Foilated. Properties of rock is another aspect for Jaspillite vs Trondhjemite. The hardness of Jaspillite is 3 and that of Trondhjemite is 6-7. The types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type 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 Jaspillite is white while that of Trondhjemite is bluish black. The specific heat capacity of Jaspillite is 3.20 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.Jaspillite is heat resistant, impact resistant, wear resistant whereas Trondhjemite is heat resistant, pressure resistant, wear resistant.
