Ordering of Ni into the Ml site of olivine should appreciably afect Ni partitioning beween olivine and melt, and activity-composition relations have been examined assuming deal solution behavior. Deviations from Raoult's law increase with increasing order, but varations in activity coefficients are less than l0 percent below l0 mole % Ni.
