An investigation using sedimentological characteristics of subsurface records documents the nature and changes of the rivers Kupal and Jarrahi (SW Iran), and their associated alluvial plains during the Holocene. Today, only traces of the Kupal river, located in between the rivers Karun and Jarrahi, are present. The sedimentary data, however, demons...
Article
A detailed sedimentological investigation of sixty-six cores supported by radiocarbon age determination enabled the reconstruction of the depositional environmental evolution since the end of the Late Pleistocene in the Iranian part of the Mesopotamian plain. Both fluvial and estuarine environments have been identified on the basis of the sediment...

In Belgian lithostratigraphy, the Gent Formation was previously introduced to encompass all Quaternary sandy aeolian sediments. It has been difficult to apply, however, as it was incomplete, regionally biased, and not based on sediment properties alone. To solve this problem the Gent Formation is revised both in terms of definition and subdivision....
Article
The early- and mid-Holocene deposits of the Lower Khuzestan plain at the north-eastern margin of the Persian Gulf have been investigated by means of facies analysis of sediment successions of undisturbed cores. Organic material and molluscs have been selected for dating by radiocarbon whereby possible contamination by hard-water effect is discussed...

Article
The Belgian coastal plain occupies a key position as it is located at the transition between the Southern North Sea Basin and the Strait of Dover. It is characterized by thick sequences (> 20 m) of Pleistocene terrestrial and littoral sediments. Yet the wider stratigraphical and palaeo-environmental significance of these sediments received little a...
Article
a b s t r a c t Several alluvial areas in the Lower Scheldt basin (LSB) have been subjected to geo-archaeological surveys and excavations in light of tidal restoration and nature development projects. Through the combination of a large number of radiocarbon dates and the sedimentary and geomorphological characteristics of the dated samples, several...
Conference Paper
Full-text available
Two sediment cores from the Western Belgian coastal plain are studied in the frame of the BiSpEem project, which aims at Pleistocene environmental reconstruction through comparison of bivalves from the coast and independently dated speleothems (chemical cave deposits). Pleistocene sediments from Leeuwenhof and Zoutenaaie contain numerous respectiv...
Article
Full-text available
The sedimentary evolution of the alluvial plain of the lower River Scheldt between Wetteren and Dendermonde, was studied based on more than 1000 hand borings, radiocarbon, dendrochronological and OSL dating, palynological analysis and archaeological surveys. The results show a laterally migrating river during the Late Glacial, creating large meande...
Article
The chronostratigraphic position of aeolian dunes in East Flanders (Belgium) has been under debate for decades. Until now, the only available age information consisted of a limited number of radiocarbon dates, which provided indirect sediment deposition chronologies. This paper reports on the first direct determination, by quartz-based single-aliqu...
Article
Full-text available
In light of wetland restoration projects the area of ‘het Zennegat’ (municipality of Mechelen, province of Antwerp) was subjected to a geoarchaeological survey project. This demonstrated the presence of a wide and deep fossil river channel, which aggraded during the Holocene with organic and clastic sediments. This aggradation was near completion a...
Article
The Brabantian loess is often seen as a homogeneous sediment package, deposited under cold and dry climatic conditions (Haesaerts et al., 1981). However, in 1981 two small tundra gleysols were discovered in the Brabantian loess (Haesaerts et al., 1981). To unravel other possible changes in the sedimentary system during deposition, a more detailed l...

The lithostratigraphic classification of the Quaternary deposits is based on the genesis of the sediments. The distinguished environments are marine - estuarine, fluvial, eolian and slope. The marine - estuarine deposits are restricted to certain time-intervals within the Quaternary and are limited to the northern part of Belgium. Fluvial deposits...

SEM photographs of the Turnhout Member (Lower Pleistocene), reveal a vertical cyclicity of 2 main clay-fabric types: (a) face-to-face domains and (b) edge-to-face domains, each of them indicating the existence of respectively dispersed particles deposited in a salt-water environment, the transition being marked by intermediate clay-fabric types. It...
