By observing the tree-ring-like growth records present in volcanic crystals, geologists are able to track volcanic activity and reconstruct the steps leading up to eruptions.

Through fossilized tooth enamel, scientists are reconstructing the diets and landscapes that existed millions of years ago. We really are what we eat.
The findings suggest Earth’s geological story was partly written in the stars – specifically, in the spiral arms of our home galaxy.
New analysis of silver items in the Bedale hoard reveals Scandinavians travelled to the east to trade much earlier than previously thought.
NASA’s Curiosity rover has spotted carbon-containing minerals that can tell scientists more about what ancient Mars’ atmosphere may have looked like.
Gold nuggets grow much bigger than they should – and electricity produced by earthquakes may be the reason why.
These rare rocks come in a few different types, which can tell geologists about Mars’ volcanic past and hint at its potential habitability.
Measuring the concentration of radioactive elements in a single, sand-size crystal reveals the growth of the Himalayan mountain range over time.
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.
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.
This article was based on research that has been retracted. See editor’s note.
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.
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.
This discovery will shape the hunt for life on exoplanets.
From far north Queensland to the southern tip of Tasmania, there is a common geological mechanism that links Eastern Australia’s volcanic history.
How we traced the origin of the sarsen stones.
Scientists have now dated the ‘Great Oxidation Event’ to just before the planet’s first ‘snowball’ period.
It’s not always easy to work out where Aboriginal remains came from, but science can help.
