A computer-created graphic of a river meandering and associated sediment deposits. The lighter blue represents the river’s current flow. The darker blue represents old areas of flow that have been cut off due to the river’s meandering. The striped regions along the flow paths represent sediment deposits in the form […]

Powerful explosive strombolian eruption from two vents on Pico do Fogo volcano.   ANIMATION What would a volcano — and its lava flows — look like on a planetary body made primarily of metal? A pilot study from North Carolina State University offers insights into ferrovolcanism that could help scientists interpret landscape features […]

Archean Maniitsoq structure in Greenland.

During fieldwork at the Archean Maniitsoq structure in Greenland, an international team of […]

Ancient kauri tree log from Ngawha, New Zealand. Credit: Nelson Parker Radiocarbon measurements on the remains of 42,000-year-old New Zealand kauri trees provide the basis for better calibration of geological archives of this period. The last complete reversal of the Earth’s magnetic field, the so-called Laschamps event, took place 42,000 […]
