Rare earth element content of the clay fraction from sediment core CRP-1 (Table 2), supplement to: Setti, Massimo; Marinoni, L; Lopez-Galindo, A; Aboud, A B (1998): TEM observations and trace element analysis on the clay minerals of the CRP-1 Core (Ross Sea, Antarctica). Terra Antartica, 5(3), 621-626
TEM observations on smectites and REE analyses on the clay minerals of the sediments of CRP-1 core were carried out to investigate their origin and the source rocks from which they were derive from. Smectites are mostly dioctahedral, but Fe-Mg richer than in other cores from Ross Sea. In addition, s...

TEM observations on smectites and REE analyses on the clay minerals of the sediments of CRP-1 core were carried out to investigate their origin and the source rocks from which they were derive from.
