Statement

Backscattered electron maps were obtained on a Zeiss Sigma HD Field Emission Gun analytical scanning electron microscope (ASEM). Major element maps Element maps were obtained on the same ASEM using dual Oxford Instruments X-max 150 mm2 energy dispersive silicon drift detectors. An acceleration voltage of 20 kV and dwell time of 20 ms was used. The beam aperture was adjusted to obtain optimum output count rates of 400,000 cps, enabling rapid mapping of large proportions of the samples at high spatial resolution. Raw counts were background-corrected using Oxford Instrument’s AZtec software, which was then used to generate element maps.
