“…Sedimentary records can thus provide a valuable archive for reconstruction of mechanism, magnitude, and frequency of event-related sedimentation in the past (Mangili et al, 2005). Trigger mechanisms for event-related sedimentation are generally ascribed to hydrologic, particularly Sediment dynamics and hydrologic events affecting small lacustrine systems on the southern-central Tibetan Plateau -the example of TT Lake meteorological events (Brown et al, 2000;Irmler et al, 2006;Nesje et al, 2001;Osleger et al, 2009;Schlolaut et al, 2014;Schneider et al, 2010;Sletten et al, 2003) or seismic activities (Beck, 2009;Karlin et al, 2004;Leroy et al, 2002;Petersen et al, 2014;Strasser et al, 2013). Studies mainly focus on the generation of an event calendar either for meteorological or seismic events.…”

A sedimentological, geochemical, micropaleontological, and palynological study of a lacustrine sediment record from the small TT Lake (southern-central Tibetan Plateau) shows that the background sedimentation was frequently interrupted by event-related deposits. These event-related deposits are interpreted as the result of hydrologic events that are triggered by above-average precipitation events. In total, 11 events were recorded in the TT Lake sequence. Two types can be differentiated: fluvial runoff events caused by precipitation that carried sediment in suspension into the lake and a sediment mass transport caused by torrential precipitation. The hydrologic events appear to be decoupled from long-term climate and environmental variations, but there is evidence that anthropogenic impact, in terms of pastoralism, might have favored the runoff events. The multi-proxy approach proved to be valuable and allowed for a detailed study of sedimentary processes within the lake and its watershed in order to assess their triggering processes and dynamics. The findings show the complexity of these sedimentary processes and their controlling factors, and the study aims to improve their understanding. This study is the first effort to investigate event-related deposits and sedimentary processes on the Tibetan Plateau and its triggering processes and dynamics by utilizing lacustrine sediment records.

“…8 and 9). Maximum occurrences or an abrupt growth of Picea forests (indicator of climate moistening -see Schneider et al, 2010) in ∼ 9.2, 8.3, 6.5 and 4.5 ka 14 C BP as well as a rise in NAP in 8.6, 8.0, 7.1 and 6.8 ka 14 C BP verify that inferred phases of high-energy geomorphic processes correlate with humid periods in the Holocene.…”

“…Other pollen evidence for a cool and damp phase during this period is provided by (Nicolussi et al 2005). Blue bands indicate colder phases noted in the pollen diagram Seiwald (1980), Haas et al (1998), Schmidt et al (2007) and Schneider et al (2010). Cooler and moister conditions were also widespread elsewhere in the Northern Hemisphere (Bond et al 2001;Solomina et al 2015).…”

“…Early studies by Kral (1986a) were carried out on Lago di Sant'Anna and the Danta di Cadore peat bog; the latter area was then reinvestigated by Poto (2013), who analyzed the transition from the Last Glacial Maximum to the Holocene, an interval of time not covered by the Coltrondo peat bog. The Holocene vegetation development of the area around the study site has also been covered by some other publications (such as Seiwald 1980;Kral 1982Kral , 1991Kral and Carmignola 1986;Stumböck 2000;Heiss et al 2005;Borgatti et al 2007;Schneider et al 2010;Festi et al 2014) (ESM Fig. S1, Table S1).…”

The present study aims to reconstruct vegetation development, climate changes and human impact using an ombrotrophic peat core from the Coltrondo bog in the eastern Italian Alps. Evidence from pollen, micro-charcoal, major and trace elements, and lead isotopes from this 7,900 years old peat deposit has been combined, and several climatic oscillations and phases of human impact detected. In particular, human presence was recorded in this area of the Alps from about 650 cal bc, with periods of increased activity at the end of the Middle Ages and also at the end of the 19th century, as evidenced by both human-related pollen and the increase in micro-charcoal particles. The enrichment factor of lead (EF Pb) increased since the Roman period and the Middle Ages, suggesting mainly mining activities, whereas the advent of industrialization in the 20th century is marked by the highest EF Pb values in the whole core. The EF Pb data are strongly supported by the 206 Pb/ 207 Pb values and these are in general agreement with the historical information available. Therefore, the multi-proxy approach used here has allowed detection of climatic events and human impact patterns in the Comelico area starting from the Iron Age, giving new insights into the palaeoecology as well as the course of the interaction among humans, climate and ecosystems in this part of the eastern Italian Alps.
