Abstract: Abstract Spray replies — Kent raises an interesting point regarding the proposed late Triassic multiple-impact event1. It might appear contradictory that the Manicouagan (∼100 km diameter) and Rochechouart (∼25 km diameter) impact structures possess normal and reversed geomagnetic reversals, respectively, if they were formed within hours of each other, as we suggested1. However, palaeomagnetic fields are acquired when magnetic mineral phases pass through their Curie points (the temperatures at which iron minerals assume magnetic order and remain with their magnetic moments parallel to the Earth's magnetic field at that time). Critically, this does not necessarily coincide with the time of formation of the host rocks.
