Toward the goal of providing quantitative paleoclimate information, future research will attempt to achieve fuller understanding about the mechanisms and processes involved in the pedogenic production of ferrimagnetic iron oxides as well as about the depths and time spanned by the formation of these minerals. Workers who have estimated the degree of pedogenesis by measurement of the SP fraction may next address the potential role of larger pedogenic grains. Another topic to be considered more fully in the future would address the variations in detrital magnetic contributions of the magnetic properties of loess for clues to possible paleoclimate variation in the source region [see Grimley, 1991; Hayward and Lowell, 1993; Rolph et al., 1993]. Moreover, loess-paleosol sequences in continents other than Asia can be more fully tested for potential paleoclimate records. Chemical conditions under which magnetic susceptibility in North American paleosols was enhanced [ Rousseau and Kukla, 1994; Feng et al., 1994] or diminished [ Hayward and Lowell, 1993; Begét et al., 1990] need careful attention. Trace-element geochemical study [see Muhs et al., 1990] of samples used for magnetic measurements may be a fruitful approach for information about both the detrital signal and possible post-pedogenic modifications to the magnetic record.
