Luminescence age constraints on the Pleistocene-Holocene transition recorded in loess sequences across SE Europe
Here we investigate the timing of the last glacial loess (L1) - Holocene soil (S0) transition recorded in loesspaleosol sequences from SE Europe (Ukraine, Romania, Serbia) by applying comparative luminescence dating techniques on quartz and feldspars. Equivalent dose measurements were carried out us...
