“State of the ECS”: The 2022 Review

“State of the ECS”: The 2022 Review

Hello everyone, Matthew here! As the end of 2022 draws near, it is time for us in the Seismology Division headquarters to reflect on another of the Earth’s tours around the Sun. Personally, this year has been a real rollercoaster. With everything getting back to some kind of normal, I’d forgotten that there is only …[Read More]

Was Antarctica glaciated during the Mesozoic?

Was Antarctica glaciated during the Mesozoic?

The climate of Earth’s most southerly landmass (i.e., Antarctica) has varied considerably throughout geological time. The Cretaceous (145-66 million years ago – mya) is widely considered to have been a greenhouse Earth with warmer (or at least warmish) temperatures, globally. Although, there is no direct evidence for pre-Eocene ice sheets in Antarctica, some geological and …[Read More]

Imaggeo On Monday: S-C mylonite in the Calamita Schists (Island of Elba, Italy)

Imaggeo On Monday: S-C mylonite in the Calamita Schists (Island of Elba, Italy)

S-C mylonites developed in andalusite-cordierite micaschist (Calamita Schists) in the contact aureole of the Porto Azzurro pluton. The white layers are made of quartz, while the brown layers consist predominantly of white mica and biotite. Top-to-left (East) sense of shear. Read more: Papeschi et al (2017). Heterogeneous brittle-ductile deformation at shallow crustal levels under high …[Read More]

Towards a better understanding of 500,000-years climate history in central Mexico

Towards a better understanding of 500,000-years climate history in central Mexico

  The effects of climate change on tropical regions are in parts still poorly understood, although the tropics include some of the most populated areas in the world. Now we created an age-depth model and a moisture reconstruction of the last 500,000 years from one of the oldest lakes in central Mexico, Lake Chalco. Central …[Read More]
