“…The source of total error consists of the error involved in determining the climofunction and the machine error in determining the proxy used in paleoprecipitation reconstruction (in this study the errors of χ FD /HIRM from each sub-horizon). In this study, the reconstructed precipitation is time averaged, not yearly, and there are also errors in sampling/mixing/ bioturbation which are not calculated (Balsam et al, 2011). The model is linear (MAP = 8.06 × χ FD /HIRM + 254) in this study and error is ±70 mm for the calibration (Liu et al, 2013).…”

“…This is due to the fact that the proxy used in this study contains two different parameters to lower the alterations. Balsam et al (2011) documented that a single type of proxy is unlikely to encompass all the climate-related pedogenic alterations of soil. The error can be largely reduced by combining different types of proxies from paleoprecipitation reconstruction.…”

“…are closely related with soil forming factors during pedogenesis, especially precipitation. Magnetic parameters, which are fast, inexpensive, non-destructive, and sensitive, have been commonly used as indicators of paleoprecipitation for decades, especially the mass-specific susceptibility (χ) (Balsam et al, 2004;Balsam et al, 2011;Liu et al, 2007;Liu et al, 2012;Maher, 1998;Maher et al, 2002;Maher and Possolo, 2013;Maher et al, 1994;Orgeira and Compagnucci, 2006). Maher and Thompson (1995) reported that pedogenic χ (defined as χ-χ C , where χ C represents the χ of the parent material) rises to a peak until MAP reaches about to reductive dissolution or alteration of the iron oxides.…”

“…The threshold of MAP and MAT is~1200 mm and 15°C, respectively. Balsam et al (2011) investigated the relationship between χ and precipitation from different climate zone (temperate, subtropical and tropical) and stated that χ rises with MAP from 200 to 1000-1200 mm and then drops as MAP exceeds 1200 mm. Besides χ, other magnetic parameters or ratios have also been used as precipitation proxies, such as χ ARM (susceptibility of anhysteretic remanent magnetization) (Maher et al, 2003), the ratio of χ ARM to IRM (isothermal remanent magnetization) (Geiss et al, 2008), χ FD % (Wang et al, 2015), and ratio of pedogenic goethite and hematite (Hyland et al, 2015).…”

“…First, the topsoil, which was used by most studies, may not represent the whole soil profile, as the magnetic properties of soil profile change dramatically along the vertical depth. There is also evidence that some magnetic properties of soil take little time to reach their "equilibrium value" with precipitation (Balsam et al, 2011), while other researchers have asserted that this process may take much longer time (Jenny, 1941;Singer et al, 1992). Second, both ferrimagnets (magnetite and maghemite) and antiferrimagnets (hematite and goethite) in the soil are closely related to the climate, but only ferrimagnets-related proxies are commonly used.…”

Magnetism of a red soil core derived from basalt, northern Hainan Island, China: Volcanic ash versus pedogenesis

Similar to loess‐paleosol sequences in northwestern China, terrestrial sedimentary sequences (red soils) in southern China also provide sensitive Quaternary records of subtropical/tropical paleoclimate and paleoenvironment. Compared with red clay sequences originated from eolian dust, red soils derived from bedrock have received little attention. In this study, a long core of red soil derived from weathered basalt in northern Hainan Island, China, was systematically investigated by using detailed magnetic measurements and rare earth element analyses. The results show that an extremely strong magnetic zone with a maximum magnetic susceptibility (>10 × 10−5 m3 kg−1) is interbedded in the middle of the core profile. This layer contains a significant amount of superparamagnetic magnetite/maghemite particles that primarily originated from volcanic ash, with secondary contributions from pedogenesis. The former has an average grain size of ~19 nm with a normal distribution of volume, and the latter has a much wider grain size distribution. The presence of volcanic ash within the red soil indicates that these Quaternary basalts were not formed by continuous volcanic eruptions. Moreover, the magnetic enhancement patterns differ between the upper and lower zones. The upper zone is more magnetically enhanced and experienced higher precipitation and temperature than the lower zone. Discrimination of superparamagnetic particles originating from pedogenic processes and volcanic ash thus provides a sound theoretical base for accurate interpretation of magnetism in red soils in this region.

The loess sequences in Tajikistan are an important archive of information about the development of climate and atmospheric circulation in central Asia during the Pleistocene. Here we present the results of an iron mineralogical study of a loess sequence in Tajikistan to reconstruct paleoclimate evolution during the mid‐Pleistocene and late Pleistocene. The record indicates that interglacial intervals were relatively humid and glacials were dry. We propose a shift in the character of the interglacial climate of the region to more humid after beginning of MIS 9; however, temperature was relatively stable. The location and intensity of Westerlies have a close link with Asian Summer Monsoon (ASM) circulations. From the beginning of MIS 9, there was a southward movement of the Westerlies circulation, which corresponded to a retreat of the Indian Summer Monsoon (ISM). A similar relationship also existed between the East Asian Summer Monsoon (EASM) circulation and the Westerlies, which is evidenced by the formation of the most weakly developed soil unit in the EASM‐dominated regions during MIS 9, in contrast with the formation of the most strongly developed soil unit in the Westerlies‐dominated regions. As conditions in the areas of loess deposition became more humid, the sedimentary basins which are the dust source areas became progressively more arid. The aridification of the source areas may be the result of increased Northern Hemisphere ice volume and accelerated high mountains and/or plateaus uplift in the surrounding regions.
