Kurzfassung
Mars is characterized by a strong crustal magnetic field, particularly over its southern hemisphere, which is believed to be the remnant of an ancient core dynamo. The dynamo ceased operating approximately 4 Ga ago, although the exact time is still under debate. The scope of this study is to introduce constraints on the possible timing of its cessation by studying the magnetization signatures over some craters which have reliable crater retention ages and are large enough for the impact to have reset the crustal magnetization within.
