Late Glacial to Holocene trace metal isotope, (bio-)geochemical, tephrochronologic, and chronologic data from the DEEP sediments of Lake Ohrid (Macedonia, Albania)

Uranium isotopes ((²³⁴U/²³⁸U) activity ratios) were analyzed at 16 cm resolution by means of multi-collector inductively coupled plasma mass spectrometry after sequential leaching to remove any non-detrital matter, sample dissolution and column exchange chromatography to isolate Uranium from the matrix.

Gas sorption analyses were conducted on leached material of selected samples to identify potential controls of surface properties and surface areas (m²/g) on uranium isotope variability, and to calculate sediment residence times of detrital matter in concert with (²³⁴U/²³⁸U) activity ratios. Sediment residence times encompass the time of detrital matter storage in the weathering horizon and fluvial transport prior to final deposition in the lake basin.
