Multianvil experiments were conducted at 1400 to 1600 8 C on olivine and peridotite starting compositions to determine the partitioning of Ti, Al, Cr, Ni, Ca, and Na between coexisting olivine and wad...
Solid-solid reactions mediated by a gas phase: An experimental study of reaction progress and the role of surfaces in the system olivine+iron metal
Solid-solid reactions olivine+iron metal
