High-resolution imaging of the melt distribution in partially molten upper mantle rocks: evidence for wetted two-grain boundaries

G. Garapić, U. H. Faul, E. Brisson
2013 Geochemistry Geophysics Geosystems  
The wetted grain boundaries at a dihedral angle >0 for this system are inferred to be due to slow expulsion of melt from dynamically reorganizing grain boundaries during steady state grain growth.  ...  The attenuation peak observed in forced torsional oscillation experiments on similar samples is likely related to the wetted grain boundaries.  ...  With estimated grain sizes from 1 mm to 1 cm, the layer thickness of wetted grain boundaries in the upper mantle needs to be in the range from 100 nm to 1 mm for observable melt-related attenuation at  ...
