“…It is noticeable that the grain-size data shows good agreement with the pollen-based inference of the humidity change in these three profiles. In general, the lower average granularity usually indicates a wet environment over the lake region, such as Caotan Lake and Sichang Lake [Chen et al, 2004]. But the indication significance of sediment grain sizes in Daxigou is different from that in Caotan and Sichang Lakes.…”

“Medieval Warm Period” is used to describe a past climate epochs in Europe and neighboring regions from the ninth to the fourteenth centuries. In order to discuss the palaeoclimate changes during the MWP on the northern slope of central Tianshan Mountains in Xinjiang Autonomous Region, northwestern China, three Holocene sediment profiles in Daxigou region, Caotan Lake and Sichang Lake located in different elevations and vegetation zones were chosen for further discussion. A multi‐proxy reconstruction of the climate change in these three profiles using pollen, phytolith records, and the data of loss of ignition (LOI), grain size, and susceptibility showed that the climate was humid during the period corresponded in time with the MWP (from the middle of the Tang Dynasty to the middle of Yuan Dynasty). Complemented by tree‐ring record, other pollen records, data of plant seeds and historical documents; we conclude that during the MWP the climate was humid on the north slopes of Tianshan Mountains in Xinjiang.

“…The granularity test indicates that the sediments are mostly silty clay, clayey silt and sandy silt. The coarse grain represents plentiful rainfall, humid climate and strong hydrodynamic conditions, while the finest grains represent less rainfall, dry climate and weak hydrodynamic conditions (Chen et al, 2003). As shown in Fig.…”

“…Chen et al (2000Chen et al ( , 2003 investigated the palaeoenvironmental features of the Daihai barrier lake by taking core samples between 12.34 and 14.18 m in depth (age: 10.5 ka BP). Wu et al (2000) and Zhu et al (2004) obtained a function between the total organic carbon and its isotope records in the Xingcuo Lake sediments and the corresponding precipitation and temperature.…”

Abstract. Studies on the formation of the ancient Diexi barrier lake on the Mingjiang River, southwestern China, have long been carried out. However, investigations into the correlation between the palaeoclimate and palaeoenvironment and the palaeoseismic events in this area are rarely found in literature. The present study took sediments from the ancient Diexi barrier lake to investigate the palaeoclimate, palaeoenvironment and palaeoseismic events. A drilling at the centre of the barrier lake was conducted and the core of about 260 m long was examined. The palaeoclimate and palaeoenvironment indicators (sporopollen, carbon and oxygen isotopes, organic matter, calcium carbonate, granularity) from the sediments have been tested and analysed, and indicate that there were 10 climatic and environmental periods between 30 000 and 15 000 a BP (before present). The discovered disturbance segments in the core indicate there were at least 10 seismic events during that period. The consistency between climate change and seismic events indicates that a strong seismicity is normally accompanied by a climatic variation. This may be a useful supplement for climate and geohazard predictions in the future.

“…It is widely accepted that coarser sediments indicate a lower lake level and drier climate, and finer sediments a higher lake level and wetter climate. However, other studies found a positive relation between grain size and precipitation [13][14][15][16]. In a glacier-fed lake, grain size may indicate temperature indirectly.…”

“…From the above results, the environmental significance has multiple solutions. To clarify such complicated relations, the main method of the paleolimnologist is to compare different proxies of time series or at best, proxies and observed data [13,17,22]. Direct evidence from the modern sedimentary process is insufficient [23], resulting in uncertain explanation of results [24].…”
