Inclusion (mineral)
From Academic Kids
In mineralogy, an inclusion is any material that is trapped inside a mineral during its formation.
Inclusions are usually other minerals or rocks, but may also be water, gasses or petroleum. In the case of amber it is possible to find insects and plants as inclusions.
The analysis of atmospheric gas bubbles as inclusions in ice cores is an important tool in the study of climate change.
Contrast with xenolith.
