Little is known about the identity of mercury methylating microbial organisms and the environmental factors controlling their activity and distribution in lakes. Our research conducted in Lake Geneva demonstrated that the ferruginous geochemical conditions prevailing in the vicinity of a waste water…

When magma prevents volcanic eruptions
November 29, 2017

Why does the floor of calderas lift disproportionately without erupting? An international team of researchers, including UNIGE members, used thermal and experimental models to explain one of the least-understood processes in volcanology: ‘caldera resurgence’.

Lakes could be an unsuspected source of greenhouse gases
November 22, 2017

Lakes and freshwater systems account for over 20% of all methane emissions into the atmosphere. Until recently, it had been thought that methane could only be produced in oxygen-deprived environments, such as the sedimentary layers found at the bottom of lakes. In reality, surface water, even though…

Successful termination of scientific drilling in South Africa
November 2, 2017

In a joint research effort between the research groups of Prof. Urs Schaltegger (Earth Sciences of University of Geneva) and Dr. Frits Hilgen (Earth Sciences of University of Utrecht), a scientific drilling project has been carried out in South Africa. The 325 meter-long drill core through the ca. 2…

Climate change can goad volcanoes into life
September 26, 2017

The possibility that temporary closure of the Gibraltar gateway and isolation of the Mediterranean from the Atlantic during the Messinian Salinity Crisis (5.96 My ago) led to near complete desiccation of the Mediterranean has been debated for more than four decades, but no definitive proof of this h…

New paper unravels the composition of Earth’s continental crust 3.5 billion years back in time
September 25, 2017

A new study by Greber et al. shows that the most abundant rock in Earth’s continental crust 3.5 billion years ago was similar to the granitic peaks from Yosemite National Park (USA). Photo: Basil Greber

A pervasive tropical climate in SE Tibet 35.5 Ma ago
September 18, 2017

A global cooling of the Earth climate has characterized the Eocene-Oligocene transition that initiated the Antarctic glaciation ca. 33.7 Ma and a shift from greenhouse to icehouse conditions. What was the impact of these climatic changes in the continental realm, particularly in tropical regions aff…
