NanoPaleoMagnetism

It’s time once again for the annual trip to the American Geophysical Union meeting – the largest gathering of geoscientists on the planet. This year the meeting moves to  New Orleans, and to celebrate we have a bumper crop of NPM group talks and posters, as well as several contributions involving our international collaborators. In no particular order, our contributions are listed below. They include mineralogical and paleomagnetic studies of the oldest materials on Earth, the discovery of the mechanism controlling the formation of ultra fine magnetite in sediments, a study of the response of magnetotactic bacteria to one of Earth’s most extreme past climate change events, and the most detailed analysis to date of the chemical and crystallographic architecture of iron-nickel meteorites. Click on the links to find out what we’ve been up to. Better still, come and see us in New Orleans (if we can drag the PI out of the blues clubs!).
