... and by quantifying the cohesion of layered deposits in the Arabia Terra region. We demonstrate that variations in dust cover associated with relative erodibility and eolian abrasion can be inconspicuous controls on apparent thermal inertia. We ultimately find that these deposits are not as cohesive as would...

Moreover, we speculate that the spherical hematitic “blueberries” on Mars ( Squyres et al., 2004 ) and perhaps the Hm in Martian dust ( Christensen et al., 2001 ; Fraeman et al., 2013 ) incorporate...
