Nya bevis pekar på framväxande tektonisk rift i Zambia

12 maj 2026

Rapporterad av AI

Gaser från varma källor i centrala Zambia visar tecken på att mantelvätskor stiger mot ytan, vilket tyder på en kontinental rift i ett tidigt skede. Forskare menar att detta kan markera starten på en ny tektonisk plattgräns. Fynden baseras på prover som samlats in i Kafue Rift.

Kafue Rift utgör en del av en 2500 kilometer lång zon som sträcker sig från Tanzania till Namibia. Geologer har länge noterat dess låga gravitation, höga underjordiska värme och mindre jordbävningar, men har fram till nu saknat direkta bevis på djupgående aktivitet. Analyser av helium- och kolisotoper från fem varma källor och tre brunnar matchar signaturer från upp till 190 kilometers djup under jordskorpan.

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.
