Mid-ocean ridges have cross-axis asymmetry; explanations have been unsatisfactory. A new publication by @AdinaPusok et al. shows that chemical (density) fractionation by melt segregation can amplify convection, break symmetry and explain observations. https://doi.org/10.1093/gji/ggac309
You are rightly sceptical that sea-level variations associated with glacial cycles pace the creation of abyssal hills. But have you read the latest by Huybers et al (co-author Katz)? New models and spectra that might convince you. https://www.pnas.org/doi/full/10.1073/pnas.2204761119
FoaLab is advertising a 1-year, ERC-funded research position intended for Ukrainian scientists. Research topic is flexible but should be related to the mechanics of liquid–solid systems. 🇪🇺🇺🇦 Anyone can apply. Details are here https://tinyurl.com/rift-o-mat-ukraine.
Speed and style are fundamental, at least for magma transport. Our Annual Reviews paper helps you and your students understand the latest constraints, hypotheses, and questions about magma transport through the mantle and into the lithosphere. @tokeller https://doi.org/10.1146/annurev-earth-032320-083704
Saturn's tiny, icy moon Enceladus manages to stay partially molten. How? A new paper by Marc Rovira-Navarro (w/ co-author Katz) asks whether tidally driven porous flow in the core dissipates the required heat. Answer: probably not. https://doi.org/10.1029/2021JE007117
The #MEREMA school on mantle dynamics is in full flow with a great programme. Magma dynamics lectures on Thursday by Yanick Ricard and Richard Katz. Thanks organisers and sponsors @soc_min_pet @SocGeol @EuroGeosciences @AgilentT @UniGenova and others.
The FoaLab welcomes Dr Tim Davis to the University of Oxford. Tim finished a PhD at GFZ earlier this year and joins the ERC-funded RIFT-O-MAT project at Oxford. He is an expert in magma-driven fracture and diking.
