Loess: Rock, sediment or soil – What is missing for its definition? doi

Loess is commonly defined as an accumulation of windblown silt. However, the complex mechanisms that are responsible for most of the structural characteristics of loess require a more precise explanation. The common definition of loess ignores a set of processes that start during and after the subaerial deposition of silt. The term loessification has been used by a number of authors to refer to the quasi-pedogenic/quasi-diagenetic processes that result in the typical aggregation of loess; however these...

Danube loess stratigraphy — Towards a pan-European loess stratigraphic model. doi

The Danube River drainage basin is the second largest river catchment in Europe and contains a significant and extensive region of thick loess deposits that preserve a record of a wide variety of recent and past environments. Indeed, the Danube River and tributaries may themselves be responsible for the transportation of large volumes of silt that ultimately drive loess formation in the middle and lower reaches of this large catchment. However, this vast loess province lacks a unified stratigraphic scheme....

Influence of HCl pretreatment and organo-mineral complexes on laser diffraction measurement of loess-paleosol-sequences doi

The influence of different sample pretreatment methods on grain size distributions in particle size analysis has been subject to controversial discussions. Standard sample preparation typically comprises the disaggregation of aggregated and agglomerated particles into single primary particles, i.e., the organic binding material is oxidized by hydrogen peroxide (H2O2) and the contained carbonates are dissolved by hydrochloric acid (HCl). The aim of this study is to evaluate the effects of HCl treatment on...

The earliest Aurignacian in Romania: New investigations at the open air site of Româneşti-Dumbrăviţa I (Banat)

Previous archaeological research in the Banat area (South-western Romania) resulted in the definition of a chronologically late Krems-Dufour type Aurignacian, followed by the isolated find of several considerably old anatomically modern human (AMH) remains at Oase Cave, several decades later. The last find set the stage for new stratigraphic, chronological and archaeological reassessment of Banat Aurignacian settlements at Tincova, Coşava and...

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...

Trapped in terms - the Protoaurignacian and early Aurignacian of Northern Spain

57th Annual Meeting of the Obermaier Society at Heidenheim 2015. Special Session on Symbolic communication and modern culture Yvonne Tafelmaier* (Mettmann) – Trapped in terms - the Protoaurignacian and early Aurignacian of Northern Spain Beyond doubt the appearance of the Aurignacian marks a turning point in the history of human evolution. By stressing the techno-typological differences, the Proto-Aurignacian on the one hand and the early Aurignacian on the other hand are said to reflect two...

A QGIS plugin to interface openModeller SFB806 doi

This is a plugin for QGIS to interface the openModeller software package. OpenModeller is a software framework for species’ potential distribution modelling. The package includes (among other program files) the om_console.exe executable which is used for the modelling process. The program file is controlled by a configuration file and needs several files as input data. The configuration file contains the paths to the input data, configuration parameters for the output data and the selected modelling...

LGM paleoenvironment of Europe - Map SFB806 doi Spatial

The here documented GIS map and dataset contains a collection of Last Glacial Maximum (LGM, ~21k yBP) paleoenvironmental data. It is the first result of a project that aims to acquire, produce and publish GIS datasets from non-GIS based sources such as analogous maps, textual informations or figures of scientific publications for prehistoric time slices. In combination with modelling results and already available GIS-datasets related to the mentioned time frame, it should enable other researchers and...
