Analyses were performed with either a 10 μm (pyroxene) or a 1 μm (olivine) beam at 15 kV accelerating potential and a current of 15 nA. Peak counting intervals were 10 s for Na, and 30 s for all other elements. For olivine (Table 2a), average major element concentrations were ...
(the main methods are multibeam bathymetry and magnetic surveys) were carried out in cruise #42 of theR/V Akademik Boris Petrovin 2017 on a large seamount at the base of the NER’s western slope near 0.5° S. The collected data also includes seismic reflection data that reveal morphology,...
