1.1 Definition

Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture

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

Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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

More about Latite and Trondhjemite

Here you can know more about Latite and Trondhjemite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Trondhjemite consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene 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 Latite vs Trondhjemite, the texture, color and appearance plays an important role in determining the type of rock. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas, Trondhjemite is available in black, brown, light to dark grey, white colors. Appearance of Latite is Rough and that of Trondhjemite is Banded and Foilated. Properties of rock is another aspect for Latite vs Trondhjemite. The hardness of Latite is 5-5.5 and that of Trondhjemite is 6-7. The types of Latite are Rhomb porphyries 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 Latite is white while that of Trondhjemite is bluish black. The specific heat capacity of Latite 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.Latite is heat resistant, pressure resistant whereas Trondhjemite is heat resistant, pressure resistant, wear resistant.
