Late Quaternary geochemical record of sediment core GeoB3375-1, supplement to: Lamy, Frank; Klump, Jens; Hebbeln, Dierk; Wefer, Gerold (2000): Late Quaternary rapid climate change in northern Chile. Terra Nova, 12, 8-13
Analyses of terrigenous sediments from the Chilean continental slope off the southern border of the Atacama desert (27.5°S), focusing on illite crystallinity and the Fe:Al ratio of the sediments, reveal a high-frequency variability of the position of the Southern Westerlies, which is very similar to...
