Xenoliths are:

A foreign rock inclusion

Explanation: The term "xenolith" is derived from the Greek words "xenos" (foreign) and "lithos" (stone). Xenoliths are fragments of rock that have been enveloped by a larger rock during the larger rock's formation and solidification. They are essentially "foreign" rocks within a host rock, hence the term "foreign rock inclusion". They are not a type of mineral, a special type of anhedral crystal, a rock composed completely of glass, or a hole in a rock filled by minerals.
