Despite recognition as one the most iconic volcanoes on the planet, there is still much to learn about Valles caldera in north-central NM. A new collaboration between researchers at the Bureau and from UT Austin is seeking to understand the events leading up to supereruptions. In particular, the team is studying the Cerro Toledo Formation, a group of volcanic domes and related ashes that erupted between the large caldera forming events at 1.61 and 1.23 million-years-ago.
This summer they met up to collect samples for geochronology and geochemical analyses that will be performed in the coming years. Click on the photos to read a bit more. This work is partially supported by the AGeS2 Program, which supports geochronology student research at labs across the US such as the Bureau’s Argon geochronology lab.
