A relict of wall rock surrounded by intrusive rock when the intrusive rock freezes.
Those are typically referred to as xenoliths. Xenoliths are rock fragments that have different mineralogy and composition compared to the surrounding rock which they are found in. They are often brought to the surface during volcanic eruptions.
Xenoliths are rock fragments from the Earth's mantle that are brought to the surface during volcanic eruptions, providing direct samples of Earth's interior. Xenocrysts are older minerals found in younger volcanic rocks, offering insights into the history of the magma before the eruption. By studying the composition and structure of xenoliths and xenocrysts, scientists can gain knowledge about the Earth's mantle, crust, and magma processes.
Xenoliths are blocks of older rock enclosed in a body of younger igneous rock.
A piece of rock embedded in igneous rock is called a xenolith. Xenoliths are typically found in volcanic rocks such as basalt or lava flows.
A xenolith is a large piece of country rock that has been broken off and/or surrounded by an igneous intrusion. As the magma intrudes the country rock it may completely surround large pieces. These pieces are then called xenoliths.

Those are typically referred to as xenoliths. Xenoliths are rock fragments that have different mineralogy and composition compared to the surrounding rock which they are found in. They are often brought to the surface during volcanic eruptions.
Xenoliths are often mafic minerals because they originate from the Earth's mantle, which is composed of mafic rocks such as basalt and gabbro. These minerals are more likely to survive the extreme conditions of volcanic eruptions, which is how xenoliths are transported to the Earth's surface. Additionally, mafic minerals have higher melting points compared to felsic minerals, making them more resistant to being melted and destroyed during volcanic processes.

Xenoliths are rock fragments that are brought to the surface during volcanic eruptions, carried within the magma from the Earth's mantle. Xenocrysts, on the other hand, are crystals that form deep within the Earth and are also brought to the surface during volcanic eruptions through the magma's ascent. Both xenoliths and xenocrysts provide valuable information about the composition and processes occurring in the Earth's interior.
