The Effect of Large Melt Fraction on the Deformation Behavior of Peridotite: Implications for the Rheology of Io's Mantle
We measured the strength of partially molten peridotites with melt contents > 10%. For a sample of olivine + 25 vol% MORB deformed in compression at 1498 K and 1523 K and 300 MPa, we calculated a viscosity of 5 × 10^15 Pa-s for 1 mm olivine grains.
