New evidence points to emerging tectonic rift in Zambia

Gases from hot springs in central Zambia show signs of mantle fluids rising to the surface, suggesting an early-stage continental rift. Researchers say this could mark the start of a new tectonic plate boundary. The findings come from samples collected in the Kafue Rift.

The Kafue Rift forms part of a 2500-kilometre zone stretching from Tanzania to Namibia. Geologists have long noted its low gravity, high subsurface heat and minor earthquakes, but lacked direct proof of deep activity until now. Analysis of helium and carbon isotopes from five hot springs and three wells matches signatures from up to 190 kilometres below the crust.

Mantle plume shaped massive Atlantic underwater canyon

Scientists have revealed that a hidden mantle plume contributed to the formation of the King's Trough Complex, a vast underwater canyon system in the North Atlantic larger than the Grand Canyon. Located about 1,000 kilometers off Portugal's coast, this 500-kilometer structure resulted from tectonic rifting between Europe and Africa millions of years ago. The findings, based on rock samples and seafloor mapping, highlight how deep Earth processes influence ocean floor features.

Earth's tectonic plates moved 3.5 billion years ago, study shows

Harvard geoscientists have found the oldest direct evidence of plate tectonics on Earth, dating back 3.5 billion years. Analysis of ancient rocks from western Australia reveals early crustal drift and rotation. The discovery, published in Science, challenges notions of a rigid early planetary surface.

Scientists create cosmic clock from zircon crystals to study ancient landscapes

Researchers at Curtin University have developed a technique using krypton gas in microscopic zircon crystals to track the history of Earth's landscapes over millions of years. The method, which relies on cosmic rays striking surface minerals, reveals how erosion and sediment movement have shaped terrains in response to climate and tectonic changes. This approach could also aid in locating mineral deposits in Australia.

Kikai caldera supervolcano shows signs of magma recharge

Researchers have found that the magma reservoir beneath Japan's Kikai caldera, site of the Holocene's largest eruption 7,300 years ago, is refilling with newly injected magma. Using underwater seismic imaging, a team led by Kobe University's Nobukazu Seama mapped the reservoir and linked it to the ancient event. The discovery offers insights into how such systems rebuild after massive eruptions.
