Komatiite forms when a volcano erupts ultramafic lava, very poor in silica and rinch in iron and magnesium. Komatiite has a higher melting point than any modern volcanic rock. Volcanoes today no longer erupt komatiite lava as Earth's interior is no longer hot enough.

Does komatiite react with hcl?

Yes, komatiite, being a magnesium-rich volcanic rock, can react with hydrochloric acid (HCl). The reaction will result in the release of hydrogen gas and the dissolution of magnesium from the komatiite rock into the acid solution. The rate of reaction will depend on factors such as the concentration of the acid and the temperature of the system.


What is the difference between Granite and Komatiite?

Granite is an intrusive felsic igneous rock. It is high in silica, potassium, aluminum, and sodium. It forms when magma cools slowly underground. Komatiite is an extrusive ultramafic igneous rock. It is poor in silica and rich in iron and magnesium. It forms when lava cools on Earth's surface. Earth's interior is no longer hot enough to produce komatiite lava.


Is komatiite intrusive or extrusive?

Komatiite is an extrusive igneous rock that forms from very hot magma erupting onto the surface of the Earth and cooling quickly. It is characterized by its high magnesium content and typically forms where there are high mantle temperatures.
