Diffraction conditions for SDF-TEM imaging as applied to the Nyseter (NYS), Sta. Eulalia (EUL), and Tysfjord (TYS) samples. The specimens are tilted from the [210]4H zone axis such that diffracted intensity is in the (00l) lattice row. The dashed circle represents the diameter of the objective aperture used for imaging, centered on the (0040)4H reflection of the substructure. In non-integral NC-pyrrhotites this reflection is weak or extinct, but occasionally occurs due to 4C domains within the diffracting volume.

SEM-BSE images of the studied pyrrhotites. (a) Sta. Eulalia (EUL) showing two sets of dark exsolution lamellae of 4C-pyrrhotite in a matrix of NC-pyrrhotite. Adjacent dark areas are also 4C-pyrrhotite. (b) Nyseter (NYS) displaying two sets of dark 4C-pyrrhotite exsolution lamellae in NC matrix. (c) Tysfjord (TYS) displaying a single set of bright troilite (2C-pyrrhotite) exsolution lamellae parallel to (001). Faint lines and striations in (a–c) are artifacts from polishing and high detector gain. (d) Accumulated BSE image of TYS and extracted intensity profile showing dark haloes around troilite lamellae. Although the spatial extent of the BSE generating region causes a considerable convolution of the image, a clear low in backscattered intensity is visible around the lamella, pointing to an approximately 1 μm wide Fe depleted diffusion zone.
