High-resolution SEM (Scanning Electron Microscope) investigations, along with high-resolution CT imaging of a 4.6 billion-year-old meteorite have revealed “fossilised” ice, showing for the first time direct evidence that when early asteroids formed they incorporated frozen water into their matrix. This has allowed Dr Epifanio Vaccaro, Curator of Petrology at the Natural History Museum, along with colleagues in Japan, to create a model of how the asteroids grew and the planets formed, including our own planet Earth.
The Petrology collection at the Natural History Museum is home to about 189,000 specimens; from the rock collection to building stones, including ocean bottom deposits. The building stone collection is one of the largest documented collections of its kind in the UK, particularly useful for matching stone in historical buildings during conservation work. Beside rock samples, it features amazing pieces of art, like this paperweight in Derbyshire black marble executed by the skilled hands of one of the most prominent nineteenth-century marble makers of the time Thomas Woodruff.
Continue reading to learn more about the marble masons in Derbyshire, the stone itself, the techniques used to create the objects, and the many other works of art created out of this stone such as Samuel Birley’s table in the V&A collection.
Some rare treasures are hidden within the Petrology collection of the Natural History Museum, and this brunch of a bush, encrusted with sinter, which formed prior to 1886 around hot springs on the shores of the old Lake Rotomahana (warm lake) in New Zealand, is one of them.
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.
