“…On our profile, the diagram of maximum susceptibility axis direction was focused toward 310 • (Figure 5F), indicating that the weathered material mainly came from this direction (Parés et al, 2007). Materials transported by the Pear River are main candidates.…”

The level of chemical weathering is strongly affected by climate. We presented magnetic properties associated with element ratios from the northern part of the South China Sea to denote links between chemical weathering intensity and monsoon changes in the previous 90,000 years. The magnetic parameter IRM AF80mT /SIRM, representing the variations of high coercivity minerals in marine sediments accompanied with the Al 2 O 3 /TiO 2 and the Chemical Index of Alteration (CIA), demonstrates strong chemical and physical weathering processes during the last 84-40 kyr when intensified Asian monsoon and warm climate occurred. High susceptibility, TiO 2 content, and relatively coarser magnetic mineral grain (relatively low ARM/SIRM ratio) also suggest more terrigenous clastic flux resulting from intensified physical erosion and river transport ability. During the 40-15 kyr period, a low IRM AF80mT /SIRM as well as chemical proxies indicate weak weathering as the climate cooled and precipitation decreased.

“…Although paleocurrents may also produce a relatively well-defined magnetic lineation (e.g., Rees and Woodall, 1975;Parés et al, 2007) Furthermore, sites CJ05, CJ06, and CJ07 lie along the crest of a ~E-W trending, westward plunging syncline (Fig. 3).…”

“…Paleomagnetic core reorientation has been successfully used for a number of years (e.g., Fuller, 1969;Kodama, 1984;Shibuya et al, 1991;Parés et al, 2007). The procedure is based on determining the direction of stable remanent magnetization (either viscous remanent magnetization or primary magnetization) with respect to a common reference line that is marked lengthwise along the core.…”
