5 Formation

5.1 Formation

Wehrlite 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.

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Pseudotachylite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Wehrlite and Pseudotachylite

Here you can know more about Wehrlite and Pseudotachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Pseudotachylite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Pseudotachylite includes Iron Oxides, Pyroxene, Quartz, Stishovite, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Pseudotachylite, the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Pseudotachylite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Wehrlite is Rough and Banded and that of Pseudotachylite is Dull and Soft. Properties of rock is another aspect for Wehrlite vs Pseudotachylite. The hardness of Wehrlite is 5.5-6 and that of Pseudotachylite is 7. The types of Wehrlite are Not Available whereas types of Pseudotachylite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite is white while that of Pseudotachylite is light to dark brown. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Pseudotachylite is 0.92 kJ/Kg K.
