“…The areas that have provided the most outstanding records of eolian dust deposition based on magnetic properties are the equatorial Atlantic Ocean (Bloemendal et al, 1993;deMenocal, 1995;Maher and Dennis, 2001;Itambi et al, 2009;Just et al, 2012), the N Pacific Ocean (Doh et al, 1988;Yamazaki and Ioka, 1997;Yamazaki, 2009Yamazaki, , 2012Bailey et al, 2011), the eastern Mediterranean Sea (Dinarès-Turell et al, 2003;Larrasoaña et al, 2003a;Köhler et al, 2008;Liu et al, 2012b), the Arabian Sea (Bloemendal and deMenocal, 1989;deMenocal et al, 1991;Bloemendal et al, 1993;deMenocal, 1995;Hounslow and Maher, 1999), and the Red Sea Roberts et al, 2011) (for a review see Maher, 2011). Given the often discontinuous nature of the continental sedimentary record, these marine magnetic records of eolian dust deposition provide valuable sources of information on past climate variability in continental regions (Liu et al, 2012a).…”

“…Magnetic susceptibility is the ratio of induced magnetization to an applied weak magnetic field and is proportional to magnetic mineral concentration, which is usually a trace component of the terrigenous fraction. Because of the high sample density obtained in its measurement, magnetic susceptibility measurement can thus provide a sensitive, high-resolution record of variations in terrigenous sedimentation in pelagic or carbonate-dominated settings (e.g., Kent, 1982;Mead et al, 1986;Robinson, 1986;Bloemendal et al, 1988;Doh et al, 1988;Bloemendal and deMenocal, 1989). Interpretations of the sequence stratigraphy between Sites 819 and 821 are discussed in detail in Glenn et al (this volume).…”

Sediments recovered from the upper-slope and outer-shelf Great Barrier Reef transect (Ocean Drilling Program Leg 133, Sites 819 through 821) contain a high-resolution, 1.5-m.y. record of mixed siliciclastic and carbonate sedimentation. More than 30 multimeter-scale couplets of fining-and coarsening-upward sediments having varying proportions of carbonate and authigenic glauconite are present. These couplets stack into cyclic bundles observed in carbonate and magnetic susceptibility data that, in turn, vary systematically with respect to systems tract development deduced from sequence-stratigraphic analysis. At Site 821, these bundles and their variations clearly track relative changes in sea level for the past ~ 1.48 m.y. The data presented suggest that these various levels of cyclicity are expressed as the result of high sedimentation rates along the margin and that the dominant control on their development has been climate variations that modulated variations in sea level and terrigenous influx. The average duration of many of these cycles is in the Milankovitch waveband and is related to both fourth-(102-443 ka) and fifth-order (34-88 ka) cycles of sea-level change. These cycles are examined with respect to their lithology (color, percentage of total foraminifers, bioclasts, siliciclastics, authigenic glauconite, nannofossils, and tunicates), sequence stratigraphy, downhole log characteristics, magnetic susceptibility, and percentage of carbonate. Time series and Fourier transform results from high-resolution magnetic susceptibility and sonic velocity data suggest strong orbital forcing of the sedimentary cycles, although with differing intensities for different depositional packages and time frames. Magnetic susceptibility/carbonate cycles are interpreted as pulses of deposition of fine-grained siliciclastics during times of maximum flooding (along downlapped surfaces) and subsequent highstand progradation. These pulses dilute carbonate and contain fine-grained magnetically susceptible detrital minerals.

“…They are being used increasingly for highresolution correlation of Ocean Drilling Program (ODP) sediment cores (e.g., Ruddiman, Sarnthein, et al, 1988;Moore et al, 1988;Prell, Niitsuma, et al, 1989). In some cases they can provide such paleoceanographic information as the resolution of glacial-interglacial cycles and the detection of various terrigenous fluxes (e.g., Robinson, 1986;Bloemendal et al, 1988a;Doh et al, 1988;Hall et al, 1989).…”

The results of detailed rock-magnetic measurements of selected stratigraphic intervals at Ocean Drilling Program Leg 108 Sites 658, 659, 661, and 665 are as follows:1. At Site 658, it is likely that the entire interval was extensively affected by reductive diagenesis, resulting in the loss of fine-grained magnetite. At Sites 659 and 665, we suspect that a similar diagenetic alteration of fine-grained magnetite occurred, but that it was confined to discrete intervals. At Site 661, the uppermost 60-70 mbsf of the section appears to be relatively unaffected by reductive diagenesis; however, we suspect that the low carbonate content of sediments below were affected by oxidative diagenesis/authigenesis, resulting in the production of ultrafine-grained ferrimagnetic material.2. Preliminary spectral analyses of the uppermost 70 mbsf (i.e., unaltered) rock-magnetic record at Site 661 suggest a decrease in the frequency of magnetite grain-size fluctuations after 2.9 Ma.
