Kimberlites are the rock type that diamonds are usually found in. They are formed when a magma from deep in the mantle drills its way to the surface in a fast gaseous explosive event. Diamonds typically occur as xenocrysts within the Kimberlite matrix. the volcanic deposits are called Lamproite igneous volcanic pipes.

an ultramafic composition
What is the parent rock for Serpentine?
The parent rock for Serpentine is ultramafic rock, such as peridotite or dunite. Serpentine forms through the metamorphism of these ultramafic rocks under high pressure and temperature conditions.
classificatio of igneous rock?
felsic, intermediate, mafic, and ultramafic.
Which of the igneous rock types has the lowest silica content?
Ultramafic igneous rock contains the least silica.
Is the main mechanism for melting decompression melting of ultramafic mantle rock?
Yes, the main mechanism for melting in decompression melting involves ultramafic mantle rock. As tectonic plates move apart, the pressure on the mantle rock decreases, allowing it to melt at higher temperatures. This process is primarily responsible for the generation of magma at mid-ocean ridges and other divergent boundaries. The resulting melt is typically basaltic in composition, originating from the ultramafic materials found in the upper mantle.
