Zusammenfassung:Bystricky discusses Holtzman et al report on laboratory data that may help in the understanding of seismic data in the mantle regions. They show that melt segregation and strain partitioning in samples of olivine and melt cause a different alignment of olivine crystals than expected. The results necessitate a reinterpretation of flow patterns in partially molten regions of the upper mantle.
