<div style="margin: 0px; background-color: white;"><span style="margin:0px" class="ContentPasted0"><b class="ContentPasted0">Abstract</b>: The early martian dynamo may have played a key role in the planet’s climatic evolution and habitability, with its termination
potentially triggering the shift to Mars’s present cold and dry climate. The dynamo’s cessation also marks the end of convection in the martian core with potentially important implications for its thermal properties and composition. Although Mars’s magnetic
history is key to understanding the planet’s early climate and deep interior, several important properties of the dynamo—most critically, the timing of its cessation—remain uncertain. In this talk, I will discuss our work to understand Mars’s magnetic history
by pairing martian meteorite paleomagnetism and large impact basin magnetization modeling. Our results suggest that a long-lived but reversing martian dynamo could simultaneously satisfy constraints from old weakly magnetic impact basins, young magnetized
volcanics, and meteorite paleomagnetism.</span></div>
