As continents grind across ‘hotspots’ in Earth’s mantle, we can get volcanoes erupting on the surface. Studying these can reveal much about our planet’s evolution.
Kimberlite volcanic rock with mantle crystals (green olivine and purple and orange garnet) and fragments of country rock (light grey).
Diamonds form alongside a distinct purple companion. We studied it to reach a conclusion about how rare they might actually be.
A new geochemical discovery could lead to a cleaner way to extract the rare earth elements needed for the transition to renewable energy.

New research suggests that fire from the sky in the form of a small asteroid annihilated a city near the Dead Sea 3,600 years ago.
Indigenous artists have been engraving rock shelters for millennia - long before the Kimberley’s celebrated rock art paintings. Now the rocks’ natural coatings are yielding clues to the engravings’ creation.
Fool’s gold, or pyrite, is made of worthless iron disulfide, but can contain tiny amounts of the real thing. Using an ‘atom probe’, research has uncovered a new way gold atoms can hide in pyrite crystals.
The ruins of the Temple of Victory in Himera, which was constructed to commemorate the first battle in 480 B.C.
Are the descriptions of war passed down by ancient historians accurate? A site in Sicily provided a rare chance to fact-check stories told about two battles from more than 2,400 years ago.

Scientists have now dated the ‘Great Oxidation Event’ to just before the planet’s first ‘snowball’ period.
Working out where Aboriginal remains came from will in take researchers from several disciplines working together.
It’s not always easy to work out where Aboriginal remains came from, but science can help.
Ponds are good for more than just decorating the garden – they could be your best tool in fighting climate change.
The comet 67P/Churyumov-Gerasimenko, seen up close.
Dust can be instructive. The analysis of those collected around the comet 67P/Churyumov-Gerasimenko provided new information on the history of the solar system.
Search for glass beads to reveal the past.
Meteorite impacts can be very destructive. One that fell in Mexico around 66m years ago created a 180km crater and caused the extinction of dinosaurs while spewing debris and molten rock into the air…
Analysis of fragments of the Chelyabinsk meteorite shows it either collided with another body before hitting the atmosphere…
Carbon modelling is easier to create for surface cycles, but deep in the Earth’s crust things become a lot more difficult…
It’s time we got to the core of our planet’s early history.
As of today, the world might have changed forever. A fundamental assumption underpinning much of modern geochemistry is that the earth has the same composition as a class of meteorites called chondrites…
