“…Magnetostratigraphies in the CLP have already revealed the presence of the CM subchron (Zheng et al, 1992;Li et al, 1997). At the Lantian section near Xi'an city, Zheng et al (1992) found a short geomagnetic excursion within the upper part of the second sandy horizon L15 and regarded it as the CM event.…”

“…On the basis of the MIS number (e.g., Horng et al, 2002), the "Stage 54" event is estimated to occur at about 1.58 Ma, which is consistent with our estimated age (1.58 Ma) for the E2 excursion. Li et al (1997) also documented a geomagnetic excursion at paleosol S22 of loess sequences that overlie fluviatile sediments on seven terraces of the Yellow River in the Linxia Basin. Assuming a constant accumulation rate between the lower Jaramillo and M-B boundaries and extrapolating this rate downward, Li et al (1997) dated this excursion at 1.537-1.551 Ma and further correlated it to the "Stage 54" event.…”

“…This normal interval involves 11 successive sampling horizons and covers a 2.2-m thickness of the stratigraphy, so it may also represent the CM subchron. Li et al (1997) identified the CM subchron within the bottom of loess L15 and estimated it at 1.177 Ma by assuming a constant accumulation rate between the lower Jaramillo and M-B boundaries and extrapolating this rate downward. At the Pingliang section, we note the presence of the possible normal polarity direction within the loess L15, but Sun et al (1998) provided no explanation for it.…”

A detailed paleomagnetic and rock-magnetic investigation on the early and middle Matuyama loess-paleosol sediments has been carried out at the Baoji section, Shaanxi province, southern Chinese Loess Plateau. Our new magnetostatigraphy revises the position of the lower Olduvai boundary from L27 to S26. Seven shortlived geomagnetic excursions, tentatively named as E1, E2, E3, E4, E5, E6, and E7, have been recognized in the L13, S22, L26, L27, S29, and upper and middle parts of L32, respectively. Results of the anisotropy of low-field magnetic susceptibility (AMS) show that the studied loess-paleosol sediments retain the primary sedimentary fabric. Rock magnetic experiments reveal that the sediments from the excursional and polarity transitional intervals have the same magnetic characteristics as those from the surrounding normal and reversed polarity intervals. Assuming a constant accumulation rate between polarity boundaries, these seven excursions are estimated to be at about 1.11 Ma (E1), 1.58 Ma (E2), 1.92 Ma (E3), 2.11 Ma (E4), 2.25 Ma (E5), 2.35 Ma (E6), and 2.42 Ma (E7) Ma. The E1 and E2 in the middle Matuyama Chron can be correlated with the Punaruu and Stage 54 (Gilsa) excursions, respectively. The E4, E5, and E7 in the early Matuyama Chron can be correlated with the Réunion II, Réunion I, and cryptochron C2r.2r-1 (X-subchron), respectively. The E3 in the lower Olduvai subchron and E6 in the early Matuyama Chron have no comparable events. At present they can only be correlated with the anomalous directions observed in the Osaka Bay core (Biswas et al., 1999). Therefore, further investigations are necessary to support their global occurrences. The present result together with the two late Matuyama excursions dated at about 0.89 Ma and 0.92 Ma (Yang et al., 2004) show that the Baoji section yields at least nine Matuyama excursions which, along with the results of the study, suggests that eight excursions occur at 0.9-2.2 Ma (Channell et al., 2002), thereby providing evidence that the short-lived geomagnetic excursions may also be a basic characteristic of the geomagnetic field during the Matuyama Chron.

“…Aeolian deposition began~22 Ma in the Qin'an area, in the western part of the Loess Plateau (Guo et al, 2002a;Hao and Guo, 2007). Subsequent deposition of both aeolian red clay and loess has been on a massive scale, with up to 130 m of red clay prior to 2.6 Ma followed by up to 300 m of loess after 2.6 Ma near Lanzhou (Li et al, 1997(Li et al, , 1999, 175 m at Lingtai (Ding and Yang, 2000;Ding et al, 2002), 159 m at Baoji (Rutter et al, 1991;Liu and Ding, 1998), 135 m at Luochuan (Liu, 1985;Sun and Liu, 2000) and ca. 100 m in the Lantian area (Zheng et al, 1992; This paper).…”

The global ice volume change regulates the Earth's climate and has been characterized by 100,000 year cycles over the last 700,000 years. The Asian inland winter climate change is proposed to show primary 100,000 year cycles that mimic ice volume changes. Here we calibrate the age of a high-resolution grain size record over the last 500,000 years with a grain size age model. The results show a primary 41,000 year cycle and a weaker 100,000 year cycle during the last~500,000 years. We suggest that the primary 41,000 year cycle in the grain size record can be ascribed to the 50°N integrated winter insolation. Our findings suggest that ice volume changes have a limited effect on the Asian inland winter climate. Asian continental winter climate changes respond to the 50°N integrated winter insolation in addition to ice volume changes.
