A new technique using 81Kr can measure the age of old groundwater in arid regions. The method can be used as a proxy for past climates and weather patterns.Read More »Geochemistry, Mineralogy, Volcanology
McDougall distinguished himself as a leader in developing potassium-argon geochronology and its application to many Earth science issues, including the geomagnetic polarity timescale.Read More »Geochemistry, Mineralogy, Volcanology
Offsets in radiocarbon concentration within the ocean or between the ocean and the atmosphere are particularly useful proxies for a variety of studies.Read More »
Geochronology and thermochronology combine geochemistry, nuclear reactions, and technology to probe the history and dynamics of Earth and planetary processes.Read More »Geochemistry, Mineralogy, Volcanology
Curiosity’s two-step heating experiment of mudstone at Gale crater reveals minerals that formed in the presence of water less than 3 billion years ago.Read More »Geochemistry, Mineralogy, Volcanology
High-precision radiometric dates shed new light on the puzzling 600,000-year disparity in the timing of one of Earth’s most pivotal timescale boundaries.Read More »Geochemistry, Mineralogy, Volcanology
A study of deformed and metamorphosed rocks exposed in Tibet’s Lopu Range suggests that episodes of crustal shortening and extension during the evolution of the Himalaya are related to subduction processes.Read More »Geochemistry, Mineralogy, Volcanology
Chronology is at the heart of all geosciences, but its ubiquity has given it an image of a useful tool rather than a foundational discipline of its own.Read More »
