Middle-Late Pleistocene marine terraces and fault activity in the Sant’Agata di Militello coastal area (north-eastern Sicily)
2012
Abstract The coastal sector of Sant’Agata di Militello (north-eastern Sicily) is characterized by a flight of raised Middle-Upper Pleistocene marine terraces occurring at different heights with respect to present sea level. In particular, the geomorphological survey and the analysis of stereo-pairs of aerial photographs allowed to recognize at least five main orders of well preserved Quaternary surfaces and relative deposits mostly located at the hanging wall and at the footwall of the Pleistocene northwest-dipping Capo d’Orlando normal fault, which controlled the geomorphological evolution of the coastal area. The marine terraces show an overall good morphological continuity and are formed…
Quartz OSL dating of late quaternary Chinese and Serbian loess: A cross Eurasian comparison of dust mass accumulation rates
2019
© 2018 Elsevier Ltd and INQUA. Reconstructing dust Mass Accumulation Rate (MAR) from loess deposits is critical to understanding past atmospheric mineral dust activity and requires accurate independent age models from loess deposits across Europe and Asia. Previous correlations of loess in Europe and China have tended to focus on multi-millennial timescales, with no detailed examination of dust MAR at the two ends of the Eurasian loess belt on shorter, sub-orbital scales. Here we present a detailed quartz optically stimulated luminescence (OSL) chronology from the Serbian Titel Loess Plateau (Veliki Surduk loess core) and the Chinese Loess Plateau (Lingtai section). The luminescence ages pa…
Un site de plein air du Mésolithique ancien à Tramoyes « Sous le Port » (Ain)
2016
Der Fundplatz wurde am heute trockengelegten Lac des Echets lokalisiert, in einem sandigen Kontext alluvialen Ursprungs, der sich den OSL-Datierungen zufolge im jüngeren Spätglazial abgelagert hatte. Die ergrabene Fläche ist zu klein, um die räumliche Organisation der durch verstreute Geröll- und Feuersteingeräte materialisierten Spuren zu erfassen. Der größte Teil der Funde wird dem Frühmesolithikum des Typs Beuronien zugeordnet, zu dem einige Elemente des älteren Sauveterrien kommen. Die 14C-Datierungen ordnen diese Belegungsphasen in das mittlere Präboreal ein. Die technotypologischen Merkmale der Steinartefakte zeigen, dass beim Abbau vorwiegend Lamellen produziert werden, daneben auch …
