These samples are impact melt glass, and radiometric age dating tells us that they formed 108 million years ago.
WebThe craters are round because at the enormous velocities with which meteorites arrive, the impact resembles a local explosion, and the signature of the impact is determined by the energy released rather than by the momentum transmitted.
WebThere were also no detectable magnetic anomalies; he argued that the meteorite fragments found on the rim were coincidental. Gilbert publicized his conclusions in a series of lectures.
