Termination II, the transition from oxygen isotope substages 6.2 to 5.5 at around 130 ka, is the penultimate drastic change from extreme glacial to interglacial climatic conditions, invoking shifts in terrigenous and biogenous influx to the deep ocean. Environmental magnetic methods are applied to reveal these shifts in an ocean-spanning transect of the subtropical South Atlantic. Magnetic mineralogy, grain size, and coercivity reflect intensified eolian inflow of volcanogenic material from the Andes due to enhanced continental aridity and wind intensity during substage 6.2. An African dust supply is only observable in continental vicinity. On the Santos Plateau, magnetic attributes indicate fluvial influx of eroded flood basalts. Layers of reductive magnetic mineral diagenesis were identified only at the westernmost sites and appear to reflect paleoredox boundaries related to enhanced Corg deposition at the termination and during stage 5.5. In all unaltered sections, stage 5.5 is magnetically similar to the Holocene. ¿ 2001 American Geophysical Union |
