Transport of coexisting Ni-Cu sulfide liquid and silicate melt in partially molten peridotite

•Imaged sulfide-bearing partially molten peridotite using X-ray microtomography.•Sulfide was stranded in locally connected melt networks under static conditions.•Shear stress produced the alignment of elongated silicate melt and sulfide pockets.•Liquid alignment oriented at 10–20° to shear plane, hundreds of microns in length.•Silicate melt provides efficient transport pathway for sulfide driven by stress.
