With guests from at least three corners of the world, the career of Professor Fernando Corfu was celebrated with a symposium and dinner at the Norwegian Academy of Science and Letters Friday 13th of September 2019. Present and former colleagues and collaborators of Fernando were invited to give talks on various topics with (geo)chronology as a common theme.
Studying gas samples from active hydrocarbon fields could be considered a routine task, however, throw a nearby active volcanic arc into this mix and you’ll be in for a few surprises. A new LUSI Lab CEED-INGV collaborative study published in JGR: Solid Earth, reveals that hydrocarbon reservoirs in NE Java, Indonesia, are connected through a system of faults to the neighbouring Arjuno-Welirang volcanic complex. The work, led by CEED PhD student Alexandra Zaputlyaeva, used geochemical measurements of gases and subsurface geophysics to trace out the migration pathways.
Similar to using a big spoon to stir a pot of tomato sauce, sinking tectonic plates into the Earth’s mantle generate flow patterns. And if you shift stirring styles then the mantle will be mixed together in a different way. A new study by CEED researcher Valentina Magni, published in Earth and Planetary Science Letters, shows how mantle flow can cause changes in melt production and composition at volcanic arcs.
Today Mars is dry, cold and has an atmosphere a hundred times thinner than the Earth’s. However, more than 3.7 billion years ago Mars was likely more humid and warmer than our planet today. But how was this possible? A new study by Benjamin Bultel and coworkers from CEED, IMPMC (Institut de Minéralogie, Physique des Matériaux et Cosmochimie) and IAS (Institut d’Astrophysique Spatiale), published in the Journal of Geophysical Research-Planets, has discovered a new piece of puzzle of the early Mars climate. They found that surface carbonates formed in a CO2-rich atmosphere that was much thicker than present.
The world's oceans are blanketed in sediments - in some places the sedimentary cover is very thick and in other places it is just a mere sprinkling. New work by CEED and international collaborators reveals a new and improved map of sedimentary thickness for the world's oceans, and it reveals far more sediments than previously thought!
