Pollen and non-pollen palynomorphs counts from Lake Fazilman, Uzbekistan
Data Publisher for Earth & Environmental Science
This data table contains the raw pollen and non-pollen palynomorphs counts of a 227 cm-long core core from Lake Fazilman (Fazilman kul, 40.550406 N, 66.589361 E; 1637 m a.s.l.), collected in July 2021 with a 50 cm Russian corer. Pollen was extracted from the sediment samples using standard procedure: (1) carbonate removal with 10% HCl, (2) silicate removal with 10% HF, (3) heavy liquid separation using ZnCl2 and HCl (density 1.1-1.3), (4) filtration after NaOH, and (5) acetolysis to eliminate cellulose and residual organic matter. Samples were stored in glycerin and counted using a BRESSER Science Infinity microscope at 40x and 100x magnification. Full details follow Dugerdil et al., (2025). Absolute concentrations can be calculated using the exotic Lycopodium spores added to each sample (batch 140119321). This information is given is the 4th column of the data table. The sample depth is given in centimeters and the age in year calibrated BP (age-depth model performed with BACON and the IntCal20 calibration curve based on 15 radiocarbon dating; Blaauw et al., 2011; Reimer et al., 2020).
