Peck, J.A., P. Khosbayar. 2002. Mid to Late Holocene climate change in northcentral Mongolia as recorded in the sediments of Lake Telmen. Palaeogeography, Palaeoclimatology, Palaeoecology Vol. 182, pp. 135-153
A record of climatic change has been reconstructed for the past 7110 calibrated calendar (cal) years for Lake Telmen, Mongolia, based upon sedimentologic and geomorphic evidence from the lake-watershed system. Lake Telmen is a saline (presently 4 g l-1) closed-basin lake and is therefore sensitive to changes in effective moisture balance. Between 7110 and 6260 cal yr ago, conditions in the Lake Telmen region were hyperarid and a small saline (approximately 20 g l-1) lake was present. Increased effective moisture balance but still arid conditions prevailed between 6260 and 4390 cal yr ago. Since 4390 cal yr ago, generally more humid conditions prevailed in the Lake Telmen region. As the lake deepened, a hypoxic hypolimnion became established below a well-developed summer thermocline resulting in varved sediment accumulation since 4390 cal yr ago. Between about 2710 and 1260 cal yr ago, a greater than present-day effective moisture balance is recorded by a series of four lake highstand terraces. Sedimentologic profiles from lacustrine cores suggest an increase in effective moisture during the past approximately 680 cal yr.
STUDY NOTES: Data from cores TN98C2, TN99C1 and TN99C4 from Lake Telmen, Mongolia. Data include sedimentary physical property values for core TN98C2, plus wet bulk density values, loss-on-ignition, pollen and diatom values, carbonate content, and radiocarbon dates for cores TN99C1 and TN99C4.
