1.1 Definition

Shonkinite is a rare, dark-coloured and intrusive igneous rock which contains augite and orthoclase feldspar as its primary constituents

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.

5 Formation

5.1 Formation

Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.

More about Shonkinite and Trondhjemite

Here you can know more about Shonkinite and Trondhjemite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shonkinite and Trondhjemite consists of mineral content and compound content. The mineral content of Shonkinite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz 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 Igneous Rocks. When we have to compare Shonkinite vs Trondhjemite, the texture, color and appearance plays an important role in determining the type of rock. Shonkinite is available in brown, buff, cream, green, grey, pink, white colors whereas, Trondhjemite is available in black, brown, light to dark grey, white colors. Appearance of Shonkinite is Banded and Foilated and that of Trondhjemite is Banded and Foilated. Properties of rock is another aspect for Shonkinite vs Trondhjemite. The hardness of Shonkinite is 5.5-6 and that of Trondhjemite is 6-7. The types of Shonkinite are Not Available 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 Shonkinite is white while that of Trondhjemite is bluish black. The specific heat capacity of Shonkinite 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.Shonkinite is heat resistant, impact resistant, wear resistant whereas Trondhjemite is heat resistant, pressure resistant, wear resistant.
