Impacts of climate and humans on the vegetation in northwestern Turkey: palynological insights from Lake Iznik since the Last Glacial doi Spatial

The Marmara region in northwestern Turkey provides a unique opportunity for studying the vegetation history in response to climate changes and anthropogenic impacts because of its location between different climate and vegetation zones and its long settlement history. Geochemical and mineralogical investigations of the largest lake in the region, Lake Iznik, already registered climate-related changes of the lake level and the lake mixing. However, a palynological investigation encompassing the Late...

Testing feldspar against quartz luminescence dating of the sandy loess sediments from the Doroshivtsy site (Ukraine) doi

Post-infrared infrared stimulated luminescence (pIRIR) dating has reactivated the use of feldspar minerals to date Pleistocene deposits. We compared pIRIR stimulation measured at 290 °C (pIRIR290) of coarse grain feldspar (100–200 μm) and optically stimulated luminescence (OSL) of coarse grain quartz (100–150 μm) with radiocarbon dating. The samples were taken from the lower part of the Doroshivtsy sandy loess sequence, which contains Gravettian artefact layers. The site is one of the very few sections in...

The Holocene archaeological sequence and site formation processes at Ifri Oudadane, NE Morocco

The coastal site of Ifri Oudadane is one of the most important sites in the Mediterranean Maghreb. Recent excavations have provided a stratigraphy featuring the transition from Epipalaeolithic hunter-gatherers to Neolithic food producers. This transitional process could be defined by various features. The sedimentological field description revealed a change from homogenous sediment to more structured deposits, and similar to the so-called “fumiers” that are characteristic of animal husbandry in caves and...

Optical dating of sediments in Wadi Sabra (SW Jordan) doi

At Wadi Sabra (SW Jordan) human occupation dates back to the Palaeolithic and Epipalaeolithic. Although there is stratigraphic correlation based on archaeological finds of Ahmarian origin, numerical age estimates are lacking. We applied single-aliquot optical dating of coarse grained quartz of wadi deposits and investigated the luminescence properties in detail to achieve more accurate age information about the time of human occupation. Weak luminescence signals and scattered dose distributions characterise...

Multiple environmental change at the time of the Modern Human passage through the Middle East – First results from geoarchaeological investigations on Upper Pleistocene sediments in the Wadi Sabra (Jordan) doi Temporal

Upper Pleistocene sediments at Wadi Sabra (Ma’an District, Jordan) were geoarcheologically investigated from 2008–2010. The Wadi Sabra valley system, situated east of the Dead Sea Rift and south of the ancient Nabataean capital of Petra, has preserved sedimentary deposits which are connected with several Upper Paleolithic sites. First results from sedimentological and geochemical analysis supported by archeological and radiometric dating provide evidence of fluvial and fluvio-eolian sedimentation during...

Paleolimnology of Lake Iznik (NW Turkey) during the past ~ 31 ka cal BP Spatial

Lake Iznik, situated in the Marmara region (NW Turkey), is an alkaline lake with about 300 km2 surface area, inserted in an area of typical Mediterranean climate. During the dry summer season, carbonates are precipitating from the water column. The endogen carbonate accumulation, e.g. aragonite, is expected to hold past climate information. A detailed understanding of the limnological system is required to differentiate site specific signals and responses to climatic forcing. Geochemical and mineralogical...

Continuity vs. Discontinuity. Epipaleolithic and Early Neolithic in the Mediterranean Southeast of the Iberian Peninsula Spatial

This study deals with the Neolithization process on a regional scale in SE Spain. The narrow chronological and spatial focus on the Epipaleolithic-Early Neolithic transition in Murcia, Almería, Granada and Málaga is a unique characteristic of this study. 10 lithic inventories and vessel units of five pottery assemblages of Epipaleolithic and Early Neolithic origin were recorded systematically in a database that is available in associated with the DOI 10.12853/RESDB.NESPOS.0001. Attribute...

Vegetation and climate history of the southern Levant during the last 30,000 years based on palynological investigation

Paleo-vegetation of northern Israel is reconstructed from palynological data over the Late Pleistocene and Holocene, and related to climate variation in the Levant, as well as anthropogenic impact on vegetation. Being located in the arid-to-semi-arid climatic transitional zone, the modern and past vegetation in northern Israel comprises both, Mediterranean macchia, and Irano-Turanian steppe assemblages, and thus is highly sensitive to climate change. Palynological analyses were carried out on two...

Late Neanderthals at Jarama VI (Central Iberia)? doi

Previous geochronological and archaeological studies on the rock shelter Jarama VI suggested a late survival of Neanderthals in central Iberia and the presence of lithic assemblages of Early Upper Paleolithic affinity. New data on granulometry, mineralogical composition, geochemical fingerprints and micromorphology of the sequence corroborate the previous notion that the archaeological units JVI.2.1 to JVI.2.3 are slackwater deposits of superfloods, which did not experience significant post-depositional...

Sediment sequence and site formation processes at the Arbreda Cave, NE Iberian Peninsula, and implications on human occupation and climate change during the Last Glacial doi

The Arbreda Cave provides a detailed archaeological record of the Middle to Upper Palaeolithic and is a key site for studying human occupation and cultural transitions in NE Iberia. Recently, studies of lake archives and archaeological sites presented new evidence on climate changes in NE Iberia correlating with Heinrich events. It, therefore, needs to be determined whether climate signals can be identified in the cave sequence of Arbreda, and if so, whether these signals can be correlated with...

Genesis of loess-like sediments and soils at the foothills of the Banat Mountains, Romania - Examples from the Paleolithic sites Romanesti and Cosava doi Spatial

The Paleolithic sites Romanesti and Cosava, situated at the foothills of the Banat Mountains in Romania, provide an important testament of life of the first European modern humans (Homo sapiens sapiens) during the Middle Pleniglacial. Even though these sites have been extensively excavated, little is known about the site formation of related loess-like sediments and soils. First luminescence data at the two investigated sections confirm sediments from the penultimate glacial period to the Holocene. ...
