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, small amounts of nontronites and trioctahedral smectites (probably saponites) were found. Smectite microparticles are mainly flaky, but significant percentages of hairy smectites were also recognized....
