    "abstract": "High temperature impact melt breccias from the Rochechouart (France)\nmeteorite crater record magnetization component with antipodal, normal and\nreverse polarities. The corresponding paleomagnetic pole for this component\nlies between the 220 Ma and 210 Ma reference poles on the Eurasian apparent\npolar wander path, consistent with the 214 $\\pm$ 8 Ma 40Ar/39Ar age of the\ncrater. Late Triassic tectonic reconstructions of the Eurasian and North\nAmerican plates place this pole within 95% confidence limits of the\npaleomagnetic pole from the Manicouagan (Canada) meteorite impact crater, which\nis dated at 214 $\\pm$ 1 Ma. Together, these observations reinforce the\nhypothesis of a Late Triassic, multiple meteorite impact event on Earth.",
