xenolith
Rounded, yellow, weathered peridotite xenolith in a nephelinite lava flow.

Sen and Jones's evidence comes from a xenolith, a piece of rock carried up to the surface by the magma.

One example of this is a xenolith, which is a fragment of country rock that fell into passing magma as a result of stoping.

In geology, the term xenolith is almost exclusively used to describe inclusions in igneous rock during magma emplacement and eruption.

The xenolith is dominated by green peridot olivine, together with black orthopyroxene and spinel crystals, and rare grass-green diopside grains.

This garnet pyroxenite xenolith from Sierra Nevada, Calif., is an example of the deepest products of crystallization within the magmatic belts of subduction zones.

Although the term xenolith is most commonly associated with igneous inclusions, a broad definition could include rock fragments which have become encased in sedimentary rock.
From the en.wikipedia.org
At least one xenolith fragment has been found in loose rubble at the volcano and included several quartz xenocrysts and polycrystalline quartz xenoliths in a glassy matrix with trachytic plagioclase.

- (geology) a piece of rock of different origin from the igneous rock in which it is embedded
- A xenolith (||foreign rock) is a rock fragment which becomes enveloped in a larger rock during the latter's development and hardening. In geology, the term xenolith is almost exclusively used to describe inclusions in igneous rock during magma emplacement and eruption. ...
- (xenolithic) Being or pertaining to a xenolith
- A fragment of country rock enclosed in an intrusive rock.
- Fragments of country rock (detatched by stoping) that sink into the magma. They are not fully absorbed by the magma and so remain as a mass. Some can be seen in igneous rocks. yea
- A piece of the surrounding rock that was broken off and dropped into the granite (or any other igneous intrusion) while it was still molten, from xeno "foreign" and lith "rock".
- Fragment of a rock or meteorite that formed apart from the host material.
- Fragments of rocks of extraneous origin that have been picked up by magma and are therefore foreign to the igneous rocks in which they occur.
- Is not a rock, but more a phenomenon. A Xenolith is a piece of rock that ended up inside another rock. Mostly a xenolith is part of the roof of an intrusion, that fell into the melt. ...
