Scientists discovered that volcanic arcs, including chains like the Andes and Cascades, played a crucial role in regulating atmospheric CO2 levels over the past 400 million years. This natural feedback mechanism helped maintain a stable climate, but recent human-driven emissions have disrupted this balance.
A study of Mytilus californianus shells reveals a shift in mineralogical composition over the past 60 years, from aragonite to calcite. Ocean acidification is likely responsible for this change, indicating potential impacts on marine ecosystems.
Researchers at St Petersburg State University have discovered a new mineral called petrovite with unique properties that make it promising for use in sodium ion batteries. The mineral's structural type is suitable for ionic conductivity, which could lead to the development of more efficient cathode materials.
Scientists at the University of Bonn have identified two new dinosaur species in Thailand, both distant relatives of T. rex. The creatures were efficient predators with a more primitive structure than their tyrannosaur cousin.
New research suggests that erionite's carcinogenic effect may be caused by its fibrous structure, rather than iron present in accompanying minerals. The mineralogists' findings raise questions about the role of ferrous particles in erionite's toxicity.
Dr. Rodney Ewing has made significant contributions to the field of geoscience, bridging disciplines to develop new applications and advancing science through publications. He serves on various advisory committees and policy boards, providing timely leadership in the disposal of high-level radioactive waste.
Researchers found diverse mineralogy in the South Pole Aitken basin's subsurface, suggesting pre-existing diversity in the Moon's crust and mantle. The study used data from the Moon Mineralogy Mapper to analyze light reflected from central peaks of smaller craters within the basin.
The new monograph Methods of Soil Analysis. Part 5. Mineralogical Methods presents valuable methodologies for analyzing soil minerals, including atomic force microscopy and X-ray absorption spectroscopy. These methods have applications in soil classification, environmental remediation, and nutrient cycling.
A new lunar meteorite, MIL 05035, has been discovered in Antarctica, providing a rare opportunity to study a part of the Moon's surface not visited by the US Apollo program. The meteorite exhibits unusual mineralogy and texture, offering clues about the Moon's formation and evolution.
Astronomers discover that asteroid 1929 Kollaa was once part of the larger asteroid 4 Vesta, which is believed to be the source of meteorites found on Earth. This finding helps scientists build a geologic map of the asteroid belt and understand forces that have acted on asteroids in the past.
