Dear Rebecca, with 18 wt% S in a Martian core that contributes about 20% (?) of the planets mass, bulk Mars would contain >3.6 wt% S. This is much more than in CM2 chondrites. From lithophile elements, we know that Mars is much more volatile and therefore S depleted than CM chondrites. Is there a good explanation ?

Hi Rebecca, this is a very informative and great talk. How about the Mg partitioning? Is it not much in the core? Is the exsolution of SiO2 enough to drive the dynamo? Thanks!
