HRTEM and EDS chemical mapping of Fe-Ni-sulfide grain. a HRTEM image showing the presence of a crystalline rim in the outer ~ 5–10 nm of the sulfide grain. b HRTEM image revealing lattice fringes with d-spacing values of 2.87 Å in the interior of the grain similar to (222) pentlandite and 2.94 Å and 2.57 Å in the rim consistent to d-spacing values for pentlandite, hematite, and magnetite. In addition, blue arrow shows the presence of strained regions in the grain. c HAADF image overlain with EDS maps of S and Ni. d HAADF image with Fe EDS map. e HAADF image with EDS maps of S, Ni, Fe showing the location of the line scan. f Quantitative EDS line scan indicating depletion of S and Ni, and the enrichment of Fe in the crystalline rim
