Laboratory experiments and geochemical model suggest that chlorate is very effective to oxidize reducing iron to reddish iron oxides on Mars when liquid water was present on the surface.Read More »Geochemistry, Mineralogy, Volcanology
High levels of carbon dioxide and hydrogen sulfide emitted by volcanic outgassing caused a deadly accident near Rome, Italy, in 2011, geoscientists have shown.Read More »
The radioactive remains of nuclear testing during the Cold War and from nuclear disasters like Chernobyl are still with us and can be found in some of the remotest glaciers on Earth.Read More »Geochemistry, Mineralogy, Volcanology
In lab experiments and models, researchers uncover how ash can affect the standing shock waves of erupting volcanoes. Their findings may lead to new predictions of volcanic ash hazards.Read More »Geology & Geophysics
Many tools of chemical analysis, experimentation, modeling, and theory have the potential to increase our understanding of how fracture patterns develop at different geological time scales.Read More »Geology & Geophysics
Scientists found natural asbestos minerals in one of the fastest-growing counties in the United States. The health implications aren’t clear, nor are the impacts on development.Read More »Hydrology, Cryosphere & Earth Surface
