    13 days ago - By Phys.org

    The almost 15-million-year-old Nördlinger Ries is an asteroid impact crater filled with lake sediments. Its structure is comparable to the craters currently being explored on Mars. In addition to various other deposits on the rim of the basin, the crater fill is mainly formed by stratified clay deposits. Unexpectedly, a research team led by the University of Göttingen has now discovered a volcanic ash layer in the asteroid crater. In addition, the team was able to show that the ground under the crater is sinking in the long term, which provides important insights for the exploration of...
