A rare and special rock, a piece of the upper mantle was donated to the NHM by researchers of Macquarie University, Sydney, Australia. This specimen is one piece of a large collection of mantle xenoliths that is being donated to the NHM.
Following my last post in the Curator of Petrology blog The island that disappeared, we take a closer look at the type of volcanic eruption that created the ephemeral island, the rocks produced by this type of eruption, and meet Empedocles – the submarine volcano that gave birth to Graham Island.
The NHM petrology collection holds more than 126,000 specimens of geological and historical importance. We take a look at some historically important volcanic rocks that illustrate the story of a diplomatic fight over an island that disappeared.
