Gradual aridification of the Sahara during the last 11,000 years revealed by plant wax δD analyses of Lake Yoa (Chad) Spatial

It is still an ongoing debate whether the transition of the last ‘green Sahara’ period to today’s large desert during the Holocene, the African Humid Period (AHP), was a progressive or an abrupt change in hydrological conditions. Several climate records mainly from East Africa suggest a rapid decline of moisture availability at the end of the AHP including new data from a marine sequence off the Horn of Africa (Tierney & deMenocal, 2013). Other archives including sedimentological,...

The Palaeolithic site Sima de Las Palomas de Teba, Southerrn Spain – Site formation processes and chronostratigraphy Spatial

Abstract (The Palaeolithic site Sima de las Palomas de Teba, Southern Spain Site formation processes and chronostratigraphy: The rockshelter sequence consists of 6 m thick stonerich silty clay loam including several archaeological levels with artefacts of Mousterian affinity, bone and charcoal. Stratigraphy and site formation processes were characterised by sedimentological, geochemical and micromorphological investigations. Sediments were dated using IRSL and OSL and the time of the last heating of burnt...

Luminescence dating Project D1 Rhineland Spatial

Luminescence ages and additional information about palaeodose estimation and dosimetry. Optically stimulated luminescence dating was carried out on 20 quartz and feldspar samples using different measurement protocols (OSL, postIR IRSL @ 290 °C). Most quartz samples from the Remagen site suffer from a thermally unstable medium component, therefore quartz ages are unreliable. Further post IR IRSL dating is in progress.

Luminescence dating Project C1 Spain Spatial

Luminescence ages and additional information about palaeodose estimation and dosimetry. Optically stimulated luminescence dating was carried out on 23 quartz and feldspar samples using different measurement protocols (OSL, IRSL, postIR IRSL at various temperatures). Thermoluminescence dating of heated silex was applied to 5 samples using a SAR protocol.

Luminescence dating Project B4 Turkey Spatial

Luminescence ages and additional information about palaeodose estimation and dosimetry. Optically stimulated luminescence dating of fluvial and lacustrine deposits was carried out on 6 quartz samples and 1 polymineral fine grain sample. Only little sample material was left of the three fluvial samples. Palaeodose measurements revealed zero doses from which we concluded that either the samples are modern or are not suitable for dating. No further measurements were carried out because of only little sample...

Luminescence dating Project B1 Romania Ukraine Spatial

Luminescence ages and additional information about palaeodose estimation and dosimetry. Optically stimulated luminescence dating was carried out on 31 quartz samples and 7 feldspar samples. Thermoluminescence dating of heated silex was applied to 11 samples using various measurement protocols (SAR, MAAD, SARA). Preliminary TL ages were published in Sitlivy et al. 2012, Quartar 59, 85-130. Further results are given in Schmidt et al. Journal of Archaeological Sciences (in review).

Luminescence dating Project B1 Jordan Spatial

Luminescence ages and additional information about palaeodose estimation and dosimetry. So far, 14 quartz samples were dated, further 5 quartz samples are in progress. The results are partially published (Bertrams et al. 2012, Quaternary International 274, 55-72, Klasen et al. Quaternary Geochronology)
