1 Definition
1.1 Definition
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption
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
Tuff is formed when large masses of ash and sand which are mixed with hot gases are ejected by a volcano and avalanche rapidly down its slopes.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.

Tuff vs Trondhjemite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Tuff and Trondhjemite Reserves. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. 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.. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Tuff vs Trondhjemite information and Tuff vs Trondhjemite characteristics in the upcoming sections.

Tuff vs Trondhjemite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Tuff vs Trondhjemite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tuff and Properties of Trondhjemite. Learn more about Tuff vs Trondhjemite in the next section.

Due to some exceptional properties of Tuff and Trondhjemite, they have various applications in construction industry. The uses of Tuff in construction industry include Building houses or walls, Construction aggregate and that of Trondhjemite include As dimension stone, Cement manufacture, Cobblestones, Construction aggregate, For road aggregate.

More about Tuff and Trondhjemite

Here you can know more about Tuff and Trondhjemite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tuff and Trondhjemite consists of mineral content and compound content. The mineral content of Tuff includes Calcite, Chlorite 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 Tuff vs Trondhjemite, the texture, color and appearance plays an important role in determining the type of rock. Tuff is available in brown, grey, yellow colors whereas, Trondhjemite is available in black, brown, light to dark grey, white colors. Appearance of Tuff is Dull, Vesicular and Foilated and that of Trondhjemite is Banded and Foilated. Properties of rock is another aspect for Tuff vs Trondhjemite. The hardness of Tuff is 4-6 and that of Trondhjemite is 6-7. The types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite. 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 Tuff is white while that of Trondhjemite is bluish black. The specific heat capacity of Tuff is 0.20 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.Tuff is heat resistant, impact resistant, pressure resistant, wear resistant whereas Trondhjemite is heat resistant, pressure resistant, wear resistant.
