The strong magnetic anomalies of Mars require highly magnetic sources in the crust. The bottom of the potentially magnetic layer is constrained by the Curie temperature of its magnetic carriers, and the top of the layer is constrained by the thickness of the uppermost crust that has been demagnetized by the impacts. This paper presents a systematic study of the thermal evolution of the Martian crust and the effects of eight major physical parameters on the thickness of the potentially magnetic layer in th…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
