Abstract:
During the MSM75 expedition on the Reykjanes Ridge, basaltic rocks and glass fragments were sampled using the remotely operated vehicle ROV PHOCA (Geomar) and a wax corer. Geochemical analyses have been performed on glass fragments of 171 samples, including 29 collected during ROV dives and 141 using the wax corer (VSR) and 1 sample using a grab (VVG). The major element contents of glasses were determined on a JEOL JXA-8200 Superprobe electron microprobe at GEOMAR using a 15 kV accelerating voltage on December 19th, 2018 and May 21st and 22nd, 2019. Matrix glasses were analyzed using a beam diameter of 5 μm, 10 nA beam current, and VGA 99 (USNM 113498/1) and VG-2 (USNM 111240) as standards (Jarosewich, 2002). Peak and background counting times were generally 20 s and 10 s, respectively.
