Lateglacial and early Holocene environmental dynamics in northern Lithuania: A multi-proxy record from Ginkūnai Lake

“…However, the recorded asynchronous changes of the palynological record suggest a delayed reaction of the vegetation to the above mentioned climatic warming, as a birch-predominating forest occupied the terrain at approximately 11,300 cal BP that suppressed pine and spruce from the catchment. A similar delayed reaction of the vegetation to the Pleistocene/Holocene warming was recorded in the Karelian Isthmus (Subetto et al, 2002), southeastern Russian Karelia , and in other sites within Lithuania (Stan cikait _ e et al, 2008(Stan cikait _ e et al, , 2009. Both global and regional causes, such as extended permafrost, cold surface water of the Baltic Sea and possible increase of anticyclonic circulation caused by the Scandinavian Ice sheet (Yu and Harrison, 1995;Harrison et al, 1996), were accepted as possible explanations of this phenomenon.…”

Holocene sediment record from Briaunis palaeolake, Eastern Lithuania: history of sedimentary environment and vegetation dynamics

“…The pollen, plant macrofossil and diatom survey with LOI (lossonignition) and 14 C measurements were applied for the reconstruction of the palaeoecological setting in the investigated basin because similar investigations have shown important results describing the postglacial history of numerous lakes (Šeirienė et al 2009;Stančikaitė et al 2009;Gaidamavičius et al 2011). The recorded fluctuations are discussed in a context of regional climatic variations established in the North Atlantic Climatic rim (Björck et al 1996Subetto et al 2002). The new data can be considered as reliable markers of the palaeoenvironmental history of the postglacial history in this area of Lithuania.…”

Geochemical evidence of the presence of volcanic and meteoritic materials in Late Pleistocene lake sediments of Lithuania

“…Although Lithuania is located a distance away from the Massif Central, the volcanic material can, under favorable atmospheric conditions, travel for long distances. For example, the presence of Vedde Ash (12.1 ka cal BP; Lane et al, 2012) from the eruption of the Icelandic volcano Katla is known in sediments of Lake Medvedevskoye from NW Russia (Subetto et al, 2002;Subetto, 2009). Therefore, the presence of volcanic material from the French Massif Central in Lithuanian sediments is not something extraordinary and completely unexpected.…”

“…Overall, presence of volcanic material in sediments can be identified on the basis of the presence of microscopic shards of volcanic glass and/or minerals, and also on the basis of geochemical features of sediments (cf. Subetto et al, 2002;Subetto, 2009;Andronikov et al, 2014). Products of volcanic eruptions are commonly enriched in such "volcanic" elements as REE, Zr and Hf, and their elevated concentrations in sediments suggest a presence of the volcanic material.…”
