Unlocking the Secrets of Antarctica's Volcanic Activity

Scientists from Durham University are studying the volcanic activity in Antarctica due to its unique geology, which allows access to volcanic rock not available elsewhere. In the dry valleys, exposed volcanic sills provide insight into the magma transport system. Using 3D imaging, scientists analyze magma crystals, similar to tree growth rings, to understand volcanic cycles better. Recent technological advances have improved the speed and accuracy of this analysis.
