The rock that forms from cooled magma is called igneous rock. Xenoliths are different types of rock embedded in igneous rock. ... As the molten material rises, it tears off bits and pieces of the magma pipe in which it is traveling. These bits and pieces, trapped in the magma but not melting into it, become xenoliths.

Where do xenoliths typically come from?

Xenoliths have also been found in meteorites, or rocks from outer space that have crashed into Earth. The xenoliths in meteorites were formed from collisions with other objects outside the Earths atmosphere. A xenolith is a rock trapped inside another rock. Diamonds are formed in the Earth's upper mantle.

How do enclaves form geology?

In geology, an enclave is an aggregate of minerals or rock observed inside a larger rock body. Micro-granular enclaves in felsic plutons result from the introduction of mafic magma into the magma chamber an its subsequent cooling following incomplete mixing. ...
