“…Climate plays a major role in chemical weathering processes, as water from rainfall is seen as the first order controlling agent that initiates chemical weathering and determines the intensity of major chemical reactions (White and Blum 1995;Blands and Rolls 1998;Sun et al 2010). Therefore, the chemical weathering processes are closely related to the temperature and precipitation conditions of the region, especially to precipitation and temperature fluctuations: warm and humid climates generally produce highly weathered elements in sediments due to chemical reactions, and the rates of weathering are higher than under a cold and dry climate (Lasaga et al 1994;White and Blum 1995).…”

“…A number of studies have demonstrated that major elements such as Ca, Mg and Na are considered more soluble and mobile, derived from chemical weathering and abundant precipitation, while Al, Si and Ti were considered more insoluble and resistant (Mackereth 1966;Sun et al 2010). Therefore, (Ca ?…”

“…The analytical accuracies were 0.2% for major elements and 0.05 ppm for trace elements, respectively. Output values were corrected with the loss on ignition (LOI), which was determined after combustion for 1 h at 550°C (Sun et al 2010). We normalized the elements to Al to evaluate chemical solution, hydrolysis and migration relative to Al because Al was generally considered the most insoluble (under both oxic and anoxic conditions) and common terrestrially derived element (Brown et al 2000).…”

“…Various proxy climatic records in the lacustrine sediments can reflect changes in monsoonal precipitation related to the strengthening or weakening of the EA summer monsoon, which brings a substantial amount of summer precipitation. A number of studies demonstrated that variations of major and trace elements in lake sediments are closely related to temperature/precipitationassociated variations in the lake basin (Brijraj and Birgit 2003;Karin et al 2003;Sai and Roger 2004;Jin et al 2006;Andrey and Saarinen 2008;Sun et al 2010), and therefore, past climatic changes may likewise be reflected by the geochemical characteristics. However, for the small lakes in South China, the exact relationship between climate variation and the regulation of transportation and accumulation of geochemical elements in lake sediments remains unclear.…”

This study emphasizes to testify the potential of geochemical proxies of lacustrine sediments as indicative of past climatic changes since the last deglaciation over the catchment of a small closed lake in South China. Based on the study on the core K02 from Dahu Swamp, a small lake in the eastern Nanling Mountains, we inferred that chemical features of clastic materials, which were mainly derived from the granite weathering crust and transported by surface runoff into this lake, possibly had played an important role in affecting chemical characteristics of the sediments. Wetter climatic conditions would lead to stronger chemical weathering intensity (CWI), resulting in more soluble and mobile elements being easily leached downward in granite weathering crusts and the insoluble ones being enriched in the top materials of the weathering crusts. In contrast, dry conditions would exert a converse influence. Although this study presents a different climatic implication of geochemistry from lacustrine sediments in South China from that in north-central China, the results demonstrate that chemical elements of sediments in the small lake in South China can be utilized to reflect the CWI, which was closely in association with variations in temperature and precipitation in the lake catchment.

Instrumental data indicate the occurrence of a dipolar pattern of precipitation anomalies between north China and the Yangtze River Valley (YRV), which was termed “northern drought (flood)—southern flood (drought)” scenario. It has been shown that this pattern occurred during the Medieval Climate Anomaly (MCA) and the Little Ice Age (LIA). However, there are questions about whether this dipolar pattern also occurred during the entire Holocene, and the mechanism responsible. Addressing these questions is of fundamental importance for understanding the spatiotemporal evolution of precipitation in East Asian summer monsoon region. Numerous studies of north China have demonstrated that the mid‐Holocene was humid, and the early and late Holocene were dry. However, there are relatively few equivalent studies in the YRV. To this end, we conducted detailed geochemical analysis of an AMS 14C‐dated sediment core from Lake Nanyi in the YRV. Our results indicate humid periods at Lake Nanyi occurred during 11.5–8.0 ka and from 2.0 ka to the present, while dry conditions occurred during ~8.0–2.0 ka. These results, together with published records from Dajiuhu peatland and Heshang Cave, collectively indicate in the YRV, the mid‐Holocene (~8.0–3.0 ka) was dry, while the early and late Holocene were humid, which is the inverse of the pattern in north China. Thus, we conclude there was an asynchronous evolution of hydroclimatic changes between north China and the YRV during the Holocene. We interpret this dipolar pattern as the result of ENSO variations: in a La Niña‐like state, the Western Pacific Subtropical High retreated northeastward, which would enable the rainfall belt to move northward and result in increased (decreased) precipitation in north China (the YRV). Sea surface temperature records from the Pacific Ocean and model simulations support this mechanism: a La Niña‐like state in the mid‐Holocene resulted in more (less) precipitation in north China (the YRV).
