Detection of Core-Derived Ruthenium in Hawaiian Volcanic Rocks Suggests Mantle-Core Interaction

Detection of Core-Derived Ruthenium in Hawaiian Volcanic Rocks Suggests Mantle-Core Interaction

Detection of Core-Derived Ruthenium in Hawaiian Volcanic Rocks Suggests Mantle-Core Interaction A study published in Nature on May 21, 2024, presents evidence suggesting interaction between Earth’s core and mantle. Researchers from the University of Göttingen analyzed basaltic rocks from Hawaii, focusing on ruthenium isotopes. Over 99.95% of Earth’s gold, along with other heavy elements like platinum, resides in the planet’s molten core. This core consists of two layers: a solid inner core of iron and nickel, and a liquid outer…

Geomagnetic Field and Atmospheric Oxygen: A 540-Million-Year Correlation

Geomagnetic Field and Atmospheric Oxygen: A 540-Million-Year Correlation

Geomagnetic Field and Atmospheric Oxygen: A 540-Million-Year Correlation New research reveals a strong, previously unknown correlation between Earth’s geomagnetic field strength and atmospheric oxygen levels over the past 540 million years. Both parameters exhibit parallel increases, with a notable spike between 330 and 220 million years ago. The study utilized two independent datasets: paleomagnetic data from ancient rocks reflecting geomagnetic field strength, and sedimentary records indicating atmospheric oxygen levels (e.g., charcoal abundance). A strong positive correlation was observed between these…
