Fig. 2

Backscatter electron image acquired at scanning electron microscope on polished thin section, showing the location of two Pb-rich nanoparticles in the studied sulfide droplet from Tallante peridotite xenoliths (A). Backscatter electron images and EDS elemental maps (Cu, Pb) on the two thin foil focused-ion beam (FIB) sections were analyzed by transmission electron microscopy (TEM) (B, E). Bright-field images in scanning transmission electron microscopy (STEM mode; C, F) and high-resolution TEM images (D, G) of the contact between the galena nanoinclusions and the adjacent sulfide minerals. Estimated measurements (nm) of ten spacings and corresponding lattice parameters are shown for each mineral domain. Mineral abbreviations are cpx clinopyroxene, gn galena, pn pentlandite, cp chalcopyrite, bn bornite, dg digenite.
