A 2-billion-year-old chunk of sea salt provides new evidence for the transformation of Earth's atmosphere into an oxygenated environment capable of supporting life as we know it. A sample of 2-bi…
New research has revealed how the history of life can be distorted by the ways animals decompose and lose body parts as they decay - and the ways in which decayed bodies ultimately become fossilised.…
Engineers working on Britain’s new high speed railway have discovered an ancient, sub-tropical coastline dating back 56 million years. A depiction of what the area would have looked like during the P…
Interest in human evolution has stimulated new geological work in the southern rift valley of Kenya. A new Geological Society of America Bulletin article by Anna K. Behrensmeyer and colleagues prese…
New research has revealed that a giant impact on Mars more than four billion years ago would explain the unusual amount of "iron loving" elements in the Red Planet. The surface features of …
It may not rank among the all-time greatest dramas, but the history of ice on Greenland has been a source of scientific controversy for more than a decade. Iceberg off the coast of Greenland [Credit:…
A new experiment by Iowa State University's Elizabeth Swanner that evaluates the reduction of iron in prehistoric oceans may reinterpret the conditions under which iron-rich sedimentary rock is f…
Core samples taken during an international ocean drilling expedition are yielding the most high-resolution, extended record of continental rifting ever obtained. IODP Expedition 381 collected 1.6 kil…
A scientific team has discovered the geological footprint of earthquakes and tsunamis that affected the Aysen region (southern Chile) up to 9,000 years ago. This new study improves the assessment of …
The simple story says that during the last ice age, temperatures were colder and ice sheets expanded around the planet. That may hold true for most of Europe and North America, but new research from …
South Africa's history and economy has been built on its rich natural treasures of a number of precious metals, stones and minerals. The country's mineral deposits have been created over hund…
Plumes of hot magma from the volcanic hotspot that formed Réunion Island in the Indian Ocean rise from an unusually primitive source deep beneath Earth's surface, according to new work in Nature …
Have you ever wished you could travel inside a rock? It may sound more like magic than science, but Princeton scientists have found a way to make it (almost) true. With an industrial grinder, a super…
The island chain of Hawaii consists of several volcanoes, which are fed by a "hotspot." In geosciences a "hotspot" refers to a phenomenon of columnar shaped streams, which transpo…
