Geochemical composition of tephra layers from deep sediment core MD99-2284, north of the Faroe-Shetland Channel, eastern Nordic Sea ...

Electron-probe microanalysis (EPMA). These measurements were performed at the Tephrochronological Analytical Unit at the University of Edinburgh using a Cameca SX100 electron microprobe with five vertical wavelength dispersive spectrometers, providing oxide values (wt. %) for 10 major elements (see...
