Climato-hydrological fluctuations printed in long lacustrine records in Lake Hövsgöl, Mongolia

Last glacial to post glacial climate changes in continental Asia inferred from multi-proxy records (geochemistry, clay mineralogy, and paleontology) from Lake Hovsgol, northwest Mongolia

“…5). Generally, coarse particles were supplied to the lake by surface runoff of precipitation and melt water (Kashiwaya et al, 2010). Therefore, high clay contents (relative low amount of coarse particles) before 21 cal ka BP in the cores indicate the arid conditions on the Lake Hovsgol watershed.…”

“…Paleoclimate studies using sediment samples from Lake Hovsgol have been carried out under the auspices of the Hovsgol Drilling Project (Prokopenko and Catto, 2005;Hovsgol Drilling Project Group, 2007;Hovsgol Drilling Project members, 2009;Kashiwaya et al, 2010). Environmental and biological changes during the late Quaternary Global and Planetary Change 88-89 (2012) [53][54][55][56][57][58][59][60][61][62][63] have been determined by geological, geochemical and paleontological studies using sediment cores from Lake Hovsgol (Fedotov et al, 2004;Karabanov et al, 2004;Nara et al, 2005;Prokopenko et al, , 2007Watanabe et al, 2009a;Murakami et al, 2010).…”

Centennial-Scale Environmental Changes in Terhiin Tsagaan Lake, Mongolia Inferred from Lacustrine Sediment: Preliminary Results

“…Formations of authigenic calcium carbonate have been observed in sediment cores from other Mongolian lakes such as Lake Hovsgol (Hovsgol Drilling Project Members 2009) and Lake Ugii (Schwanghart et al 2009). The formation of calcium carbonates in Mongolian inland lakes may be a good proxy of environmental climate changes (Fukushi et al 2006;Kashiwaya et al 2010;Nishiyama et al 2013). Table 2.2 lists the saturation indices of calcium carbonates.…”

Cyclostratigraphic studies of sediments from Lake Van (Turkey) based on their uranium contents obtained from downhole logging and paleoclimatic implications

“…However, higher-frequency cycles (O and P) have been interpreted in several records from Quaternary terrestrial archives (Berger and Loutre 2010;Bogota-A et al 2011;Kashiwaya et al 2010;Prokopenko et al 2006).…”

“…Even though orbital cycles have been interpreted in numerous marine records (Barthes et al 1999;Golovchenko et al 1990;Jarrard and Arthur 1989;Molinie and Ogg 1990a) and several lacustrine sedimentary sequences (Bogota-A et al 2011;Kashiwaya et al 2010; Fig. 1 a Bathymetric map of Lake Van, seismic lines from pre-site surveys and targeted drillsites within the PALEO-VAN project (Litt et al 2009).…”
