Chris Jackson braved Zone 5 of the London Underground system to give a talk to the Harrow and Hillingdon Geological Society (9th March). His talk was entitled ‘Salt of the Earth’.
As part of the Norwegian Research Council-founded MIMES (Mechanical Implications of Magma Emplacement in Sedimentary Sequences) and DIPS (Dynamics of Igneous Plumbing Systems in Sedimentary Basins) projects, on which they are both co-Is, Craig Magee (@drcraigmagee) and Chris Jackson (@seis_matters) engaged in a live ‘tweeting’ session as they interpreted one of the world’s largest sill-like igneous intrusions imaged in seismic reflection data from the NW Shelf of Australia. The ‘Chandon’ sill, so-called after the 3D seismic survey in which it is best-imaged, is 70 km long and 40 km wide. In short, it’s a monster. Follow the DIPS-MIMES project on Twitter at @magma_pulse.
