| Title | Xenoliths at Kilbourne Hole, New Mexico |
|---|---|
| Description | Kilbourne Hole is a type of volcanic feature called a maar. The maar formed by a violent, gaseous eruption about 80,000 years ago. The eruption blew much ashy debris into the air which settled to give layered deposits containing abundant xenoliths - samples from the earth's crust and mantle that were carried to the surface by the exploding magma. This photo shows xenoliths: the green specimens are a type of ultramafic rock called lherzolite, the black ones are pyroxenites, and the gray samples are crustal granulites. |
