Africa has some of the world’s most important geological landscapes, yet they remain under-represented in digital geoheritage research.
Studying the mineral olivine in kimberlite sheds some light on diamond origins.
Today, plate tectonics carry water into Earth’s depths. But this deep water cycle goes back much further.
The oldest known impact structure on Earth has been confirmed in outback Australia.
Understanding why some faults creep rather than sticking and causing massive earthquakes is important for gauging the future risk of both earthquakes and tsunamis.
The microbes living here were dramatically disrupted – and the future of life on Earth changed.
The crater dates back 3.5 billion years, making it the oldest known by more than a billion years.
There seems to be too much of a radioactive element in rocks deep in the Pacific Ocean – how did it get there 10 million years ago?
Vast amounts of space rocks litter our Solar System, and sometimes land on Earth’s surface. There are many things we can learn from them.
Life depends on Earth’s ancient continental crust – but there are only a few places where remnants of it can still be seen today.
Measuring the concentration of radioactive elements in a single, sand-size crystal reveals the growth of the Himalayan mountain range over time.
There are a lot of myths about crystals − for example, that they are magical rocks with healing powers. An earth scientist explains some of their amazing true science.
Mineralogical analysis of 5,000-year-old stone beads from Turkana, Kenya suggest a novel mortuary tradition by early pastoralists.
Some rocks will burn, and others will melt, depending on how they were formed and what minerals they contain.
Sophisticated equipment on the Perseverance rover is helping answer some of the many questions researchers have about Mars’ geology over time.
Without intervention, the rock may have been destroyed by high tides and storm surges.
A biologist explains how researchers nail down the age of ancient fossils thanks to a physical process called radioactive decay.
Crystals are part of a larger tradition of metaphysical religions that have a long history in the U.S.
Dating of rocks that once formed some of the world’s first beaches suggests the first large continents grew large enough to rise above sea level roughly 3 billion or so years ago.
Perseverance and its helicopter sidekick, Ingenuity, have been on Mars for nearly nine months. The duo have taken rock samples, performed first flights and taken images of the delta in Jezero Crater.
